IXL Review
A Johns Hopkins randomised trial says it raises maths scores. Five hundred and ninety-seven Trustpilot reviewers give it 1.1 out of 5. Both are true, and one setting explains why.
IXL
Strong Evidence, 1.1 On TrustpilotThe evidence is real and unusually strong: a randomised control trial by the Center for Research and Reform in Education at Johns Hopkins University, meeting ESSA Tier 1 and WWC Without Reservations, found IXL Math students outgained controls "by more than 10 points on the Renaissance Star Math assessment, with even higher gains for Hispanic, special education, ELL, and FARMS students". Those are the top evidence tiers in US education.
And the user verdict is brutal: 1.1 out of 5 from 597 Trustpilot reviews, on an unclaimed profile. The cause is in IXL's own help article: the SmartScore "starts at 0", and "if a question is answered incorrectly, the score decreases" — while mastery requires 100. A child at 95 goes backwards.
The fix is one sentence, in the same article: "A score of 80 is proficient, and a score of 90 is considered excellent." Set the household target at 80, cap sessions at twenty minutes, and most of the reason people hate this product disappears.
Checked 8 August 2026: single subject $9.95/month or $79/year for one child, each additional child $4/month or $40/year, one membership covering the whole family; maths plus language arts $15.95/month; four core subjects $19.95/month. Auto-renewal disclosed in capitals, four-click self-serve cancellation effective immediately with access to term end, and a 30-day money-back guarantee on purchases made directly through IXL.com.

ESSA Tier 1 Evidence From A Johns Hopkins RCT
IXL's research page states that the Center for Research and Reform in Education at Johns Hopkins University ran a randomised control trial "meeting criteria for ESSA Tier 1 and WWC Without Reservations designations", with IXL Math students outgaining controls "by more than 10 points on the Renaissance Star Math assessment". Those are the top evidence tiers in US education
And A 1.1 Out Of 5 On Trustpilot, From 597 Reviews
Not a small sample and not a rounding error. The profile is unclaimed, which partly explains the skew — no happy user is being asked to review — but 1.1 from nearly 600 people is a real signal about the experience of using it
The SmartScore Explains Both Numbers
From IXL's own help article: the score "starts at 0", and "if a question is answered incorrectly, the score decreases". Mastery requires 100. A child at 95 can be knocked backwards. That mechanic is why it teaches, and why it is resented
The Fix Is In Their Own Documentation
The same article says "A score of 80 is proficient, and a score of 90 is considered excellent." Most parents never see that sentence. Setting the household target at 80 rather than 100 removes most of the misery without losing the learning
The Evidence Is For Classroom Math, Not Home Use
The Tier 1 trial studied IXL Math implemented in schools. A parent buying a $9.95 family membership for home practice is not in that study, and the separate claim that IXL schools score 15 to 17 percentile points higher is correlational, not causal
Terms Are Genuinely Fair, Which Is Rare Here
Auto-renewal is disclosed in capitals, cancellation is self-serve and effective immediately with access to term end, and there is a "30-Day Satisfaction Guarantee" for purchases made directly on IXL.com. No pro-rata refunds for partial periods
Set It Up To Not Be Miserable
Five minutes of setup addresses most of what those 597 reviewers are complaining about.
| The Problem | Why It Happens | What To Do |
|---|---|---|
| Score goes backwards | Wrong answers decrease the SmartScore, and errors cost more the closer you get to 100 | Make 80 the finish line — IXL calls it proficient |
| Sessions with no end | Finishing is defined by a score, so a bad run has no exit | Cap by time: twenty minutes, then stop regardless |
| Skill is too hard | Pushing through a skill above their level produces repeated failure | Drop a grade level — children can work at any level |
| Another scoreboard | A child already facing weigh-ins and BMI charts does not need a second one | Frame it as practice, never as performance |
| More sitting | Adolescent treatment guidelines pair medication with activity, and this is screen time | Short sessions; ask the school for support first — it is free |
Wegovy has been approved for adolescents 12 and over since December 2022, and the AAP's 2023 guideline offers pharmacotherapy from age 12 alongside lifestyle treatment — which is why a catch-up tool belongs on this site at all. Our side-effects guide covers the nausea that costs school days.

- ✕The SmartScore decreases on wrong answers and requires 100 for mastery, which is the single largest source of complaint
- ✕That mechanic is a poor fit for a child who is already feeling measured and scrutinised about their body
- ✕The Tier 1 evidence concerns IXL Math delivered in classrooms, not the home family membership this affiliate link sells
- ✕The claim that IXL schools score 15 and 17 percentile points higher is a comparison between schools, not a causal finding
- ✕No refunds or credits for partially used membership periods once the 30-day window has passed
- ✕The terms reserve the right to vary the amount billed and to add new fees
- ✕The 30-day guarantee does not apply to purchases made through a third-party app store
- ✕The advertiser's own programme copy says "over 15 million students" while the site now says over 18 million — minor, but the brief was not current
- ✕It is more screen time and more sitting, which pulls against the activity half of adolescent obesity treatment
- ✕Nothing here is medical, educational-therapeutic or a substitute for a school's own support for a child missing lessons
- ✕Commission is 10% on Net 78 terms, so we are paid on a subscription and wait eleven weeks for it
Our Verdict
3.6 / 5 — it works, children dislike it, and one setting is the difference.
Two facts about IXL are both well established and they point in opposite directions. The first: its research page states that the Center for Research and Reform in Education at Johns Hopkins University ran a randomised control trial "meeting criteria for ESSA Tier 1 and WWC Without Reservations designations", finding that "IXL Math students outgained control students by more than 10 points on the Renaissance Star Math assessment, with even higher gains for Hispanic, special education, ELL, and FARMS students". ESSA Tier 1 is the top of four evidence tiers, requiring strong evidence from a well-designed experimental study, and "Without Reservations" is the What Works Clearinghouse's highest rating for a well-executed randomised trial. In a sector that mostly runs on testimonials, that is a serious credential — and having recently reviewed a supplement brand that invented a Johns Hopkins recommendation out of thin air, we appreciate the difference between citing an institution and actually being studied by one. The second fact: the Trustpilot profile for ixl.com sits at 1.1 out of 5 from 597 reviews, unclaimed by the company.
Neither number is wrong, and the reconciliation is in IXL's own help centre. "When a student starts practicing a skill, the SmartScore starts at 0. As the student answers questions correctly, the SmartScore increases. If a question is answered incorrectly, the score decreases." And: "A skill is mastered when the SmartScore reaches 100." That is the entire complaint. A child working towards 100 who slips at 95 loses ground, and because the algorithm weights difficulty and consistency, the last stretch is where mistakes hurt most. It is also, plausibly, why the thing teaches — you cannot bluff your way to mastery by guessing. Effective practice being unpopular is not a paradox; it is the ordinary condition of education. But it does mean you should not buy this expecting your child to like it, and you should not treat a 1.1 as evidence it does not work, nor a Tier 1 designation as evidence your evenings will be pleasant. The useful move is to change the setup, and the sentence that does it sits in the same help article most parents never open: "A score of 80 is proficient, and a score of 90 is considered excellent." Eighty. Make eighty the finish line, cap sessions at twenty minutes rather than at a score, and drop a grade level when a skill is clearly above them. That removes most of the punishment loop and keeps the practice.
There is one boundary on the evidence worth stating plainly, because the marketing does not. The Tier 1 trial studied IXL Math implemented in classrooms, with teachers assigning and monitoring the work. What this affiliate link sells is a family membership for home use, in the evening, possibly to a child who is unwell. The trial is good evidence that the content and the mastery mechanic teach maths; it is not evidence that a tired teenager on a laptop at eight o'clock will get the same result. Keep the other claim in proportion too: "IXL schools score as much as 15 percentile points higher in math and 17 percentile points higher in language arts on state assessments" compares schools that chose IXL with schools that did not, which is correlation, not the causal finding. Credit where it is due for publishing both and labelling the RCT clearly as the RCT.
Commercially it is one of the cleanest propositions we have reviewed. A single subject is $9.95 a month or $79 a year for one child; maths and language arts together are $15.95; four core subjects are $19.95. One membership covers the whole family — "There is no need to purchase more than one membership" — with each additional child at $4 a month or $40 a year, each getting their own profile and analytics. The terms disclose auto-renewal in capital letters: "MEMBERSHIP SUBSCRIPTION RENEWAL FEES WILL BE AUTOMATICALLY CHARGED TO YOUR CARD ON FILE EACH SUBSCRIPTION PERIOD (MONTHLY OR YEARLY), UNTIL YOU CANCEL." Cancellation is four clicks in the parent account, effective immediately, with access to the end of the paid term and no further charge. And there is a "30-Day Satisfaction Guarantee" for a full refund within thirty days of purchase — limited to purchases made directly on IXL.com rather than through an app store, which is the one thing to get right at checkout. There are no refunds for partially used periods after that, and the terms reserve the right to vary fees.
Why this is on a GLP-1 site: Wegovy has been approved for adolescents aged 12 and over since 23 December 2022, on the STEP TEENS trial's 16.1% mean BMI reduction, and the American Academy of Pediatrics' 2023 guideline offers pharmacotherapy from age 12 alongside intensive lifestyle treatment. Families in that position lose school days to clinic appointments and to the nausea of dose escalation, on top of the absenteeism already associated with adolescent obesity. A ten-dollar-a-month catch-up tool is a sensible answer to that. Two honest counterweights. A child already facing weigh-ins and BMI percentiles may not need a second scoreboard that visibly punishes mistakes, so weigh that if yours is anxious or perfectionist, and use the eighty rule from day one. And this is screen time and sitting, which pulls against the activity half of the treatment guideline — so keep sessions short, and ask the school first, because a school's obligation to support a child missing lessons for medical reasons costs nothing. Our disclosure: 10% on Net 78 terms, about a dollar a month, arriving in eleven weeks.
Visit IXLFrequently Asked Questions
Why is a maths website being reviewed on a GLP-1 site?
Because a real share of this site's readers are parents of adolescents in treatment, and that treatment costs school days. Wegovy has been approved for adolescents aged 12 and over since 23 December 2022, on the strength of the STEP TEENS trial which reported a 16.1% mean reduction in BMI, and the American Academy of Pediatrics' 2023 guideline offers pharmacotherapy from age 12 alongside intensive health behaviour and lifestyle treatment. So there are households where a twelve to seventeen year old is titrating up on semaglutide, and that involves things that happen during school hours: clinic appointments, blood work, weigh-ins, and the nausea and vomiting that are the commonest side effects during dose escalation. Add that obesity is independently associated with higher school absenteeism, and that untreated obstructive sleep apnoea — common in adolescent obesity, and the reason tirzepatide carries an apnoea indication in adults — impairs attention and academic performance. The result is a fairly ordinary family problem: a bright child falling behind in maths through no fault of their own, and a parent looking for a way to catch up at home without paying for a tutor. At $9.95 a month for one subject, or $15.95 for maths and English together, IXL is a reasonable answer to that specific problem. That is the whole connection, and we are not going to inflate it. This is a tutoring website. It has nothing to do with anybody's medication.
How strong is the evidence, really?
Stronger than almost anything else we have reviewed on this site, with one important boundary. IXL's research page states that the Center for Research and Reform in Education at Johns Hopkins University conducted a randomised control trial "meeting criteria for ESSA Tier 1 and WWC Without Reservations designations", and that "IXL Math students outgained control students by more than 10 points on the Renaissance Star Math assessment, with even higher gains for Hispanic, special education, ELL, and FARMS students". Those designations mean something specific. ESSA Tier 1 is the top of four evidence tiers under the Every Student Succeeds Act, requiring strong evidence from at least one well-designed and well-implemented experimental study — that is, a randomised trial. "Meets WWC standards Without Reservations" is the What Works Clearinghouse's highest rating, reserved for well-executed RCTs. An education product with genuine Tier 1 evidence is unusual; most of the sector runs on testimonials and vendor-funded correlational studies. Now the boundary, which matters for the person reading this. That trial studied IXL Math implemented in schools, with teachers assigning and monitoring it. You would be buying a family membership for home use, unsupervised or lightly supervised, in the evening, from a child who may be tired and unwell. The trial does not tell you that works. And keep the separate claim in its place: "IXL schools score as much as 15 percentile points higher in math and 17 percentile points higher in language arts on state assessments" is a comparison between schools that chose IXL and schools that did not, which is correlation. The RCT is the causal evidence; the percentile figures are not.
So why is the Trustpilot rating 1.1?
Because efficacy and enjoyment are different things, and IXL is a clear case of the two coming apart. The Trustpilot profile for ixl.com sits at 1.1 out of 5 from 597 reviews as of 8 August 2026, on a profile listed as unclaimed. Two things follow. First, the sample is skewed by construction: the company is not soliciting reviews, so nobody satisfied is being prompted, and the people who arrive under their own steam to review a homework platform are overwhelmingly students who were made to use it and parents who watched them cry over it. A 1.1 is not a measure of learning outcomes. Second, 597 self-motivated one-star reviews is not noise either, and it would be dishonest to wave it away. Something specific is generating it, and IXL's own documentation tells you what. Both facts can be true at once: a tool can raise test scores in a randomised trial and be widely disliked by the children using it. That is not even unusual in education — a great deal of effective practice is unpopular. What it means practically is that you should not buy this expecting your child to enjoy it, and you should read the next answer before you start, because most of the misery is avoidable and comes from a setting almost no parent knows about.
What is the SmartScore problem, and how do I avoid it?
The mechanic is the complaint, and IXL's own help article both explains it and hands you the fix. Quoted directly: "When a student starts practicing a skill, the SmartScore starts at 0. As the student answers questions correctly, the SmartScore increases. If a question is answered incorrectly, the score decreases." It adds that the calculation weighs "the number of questions completed, question difficulty, and consistency", and that "a skill is mastered when the SmartScore reaches 100". So a child grinding towards 100 who makes two careless errors at 95 goes backwards, and the closer to 100 they get the more each mistake costs. For a tired twelve-year-old that is the recipe for tears, and it is precisely what those 597 reviews describe. Now the sentence almost nobody reads, from the same article: "A score of 80 is proficient, and a score of 90 is considered excellent." IXL itself defines 80 as proficient. So set the household rule at 80, not 100. Tell your child that 80 is finished, write it on a note by the laptop, and do not treat 100 as the target unless they want it. That single change removes most of the punishment loop while keeping the practice that the randomised trial actually measured. Two more: cap the session by time rather than by score — twenty minutes, then stop regardless — and if a skill is clearly beyond them, move to an easier one rather than pushing through, because the platform is adaptive and there is no prize for suffering.
What does it cost, exactly?
Cheap, clear, and cheaper still for siblings. From the pricing page and the help centre, checked 8 August 2026: a single-subject family membership — maths, or language arts — is $9.95 a month or $79 a year for one child. Maths plus language arts together is $15.95 a month. The core package, adding science and social studies, is $19.95 a month. Spanish is available within the range. Crucially, one membership covers your whole family rather than one child: "There is no need to purchase more than one membership! You can purchase access for multiple children within your family membership", each with their own profile, analytics and awards, and each additional child costs only $4 a month or $40 a year. That is genuinely good value against private tutoring, which typically runs into tens of dollars an hour. On the annual maths: $79 a year for one child works out at about $6.58 a month, so the yearly plan is a meaningful discount if you are confident, and the monthly is the safer start. The 20,000-plus skills span Pre-K to Calculus in maths and Pre-K to 12 in language arts, and children can work at any grade level, which is the feature that matters most if your child has fallen behind — they can go back without it being labelled as remedial.
Are the subscription terms fair?
Yes, unusually so, and we say that as people who have spent a lot of this series finding traps. The terms of service state, in capitals: "MEMBERSHIP SUBSCRIPTION RENEWAL FEES WILL BE AUTOMATICALLY CHARGED TO YOUR CARD ON FILE EACH SUBSCRIPTION PERIOD (MONTHLY OR YEARLY), UNTIL YOU CANCEL." That is the correct way to disclose auto-renewal — prominently, and in the buyer's face. Cancellation is genuinely easy and documented step by step: sign in to the parent account, open the account menu, select Subscription details, click Cancel membership, submit. The help article confirms "You can cancel any time during your membership term, and your account will stay active until the end of that term… and you will not be charged again", and the terms add that cancellation "will be effective immediately" with access continuing to the end of the paid period. There is also a "30-Day Satisfaction Guarantee": "If you are not satisfied, a full refund of the purchase price can be requested within thirty (30) days of the Purchase Date." Three caveats to know. The guarantee applies only to purchases made directly through IXL.com, not through a third-party app store — so buy on the website, not in the App Store, if you want that protection. There are no refunds or credits for partially used periods after that window. And the terms reserve the right to change fees or add new ones, which is standard but worth knowing.
Is there a reason not to buy it for a child in treatment?
One worth taking seriously, and it is about what an adolescent in this situation does not need. A child on a weight-management medication is already being measured. There are weigh-ins, there is a BMI percentile chart, there are dose increases tied to numbers, and there is a strong chance they are conscious of being assessed in a way their peers are not. Dropping them into a platform whose defining feature is a score that visibly falls when they get something wrong is, for some children, adding a second scoreboard to a life that already has one too many. If your child is anxious, perfectionist, or has any history of disordered eating or self-critical thinking, weigh that carefully — and if you proceed, use the 80-not-100 rule from the start and frame it as practice rather than performance. The second consideration is more mundane: this is screen time and it is sedentary. Adolescent obesity treatment guidelines pair medication with intensive health behaviour and lifestyle support, and that means activity. An hour of maths practice on a laptop is an hour not spent moving. That is not an argument against catching up on schoolwork, which obviously matters; it is an argument for keeping the sessions short — twenty minutes is plenty — and for not letting a subscription you are paying for become a reason to sit down longer. And the obvious point: talk to the school first. Schools have obligations to support a child missing lessons for medical reasons, and that support is free.
What is your verdict?
3.6 out of 5. It works, a lot of children dislike it, and both of those are established rather than contested. The evidence side is the strongest we have seen in this series outside a federal regulator's court filing: a randomised control trial by the Center for Research and Reform in Education at Johns Hopkins University, meeting ESSA Tier 1 and WWC Without Reservations, reporting IXL Math students outgaining controls by more than 10 points on Star Math with larger gains for special education and English-learner students. The pricing is honest at $9.95 a month or $79 a year for one subject, with siblings at $4 a month. The terms are clean: auto-renewal in capitals, four-click cancellation, a 30-day money-back guarantee on direct purchases. Against that: 1.1 out of 5 from 597 Trustpilot reviewers, driven by a SmartScore that starts at zero, decreases on wrong answers and demands 100 for mastery. The single most useful thing in this review is that IXL's own documentation defines 80 as proficient — so set 80 as the target, cap sessions at twenty minutes, and most of the reason people hate this product disappears. And keep the boundary honest: the Tier 1 trial was of classroom maths, not of a family membership used at home by an unwell teenager, so treat it as good evidence that the content teaches rather than proof that your evening will go well. Our disclosure: 10% commission on Net 78 terms — about $1 a month on a $9.95 subscription, paid eleven weeks later.
Make 80 The Finish Line.
IXL's own help centre calls 80 proficient. Set that as the target, cap sessions at twenty minutes, and buy on the website rather than through an app store so the 30-day guarantee applies.

Nothing here should be read as guidance on whether any child should receive weight-management medication. Decisions about adolescent obesity treatment belong with the young person, their family and their clinicians; the American Academy of Pediatrics' 2023 clinical practice guideline recommends intensive health behaviour and lifestyle treatment and offers pharmacotherapy to adolescents aged 12 and over as an adjunct, and semaglutide 2.4mg was approved in the United States for adolescents aged 12 and over on 23 December 2022 on the basis of the STEP TEENS trial. Adolescents taking GLP-1 receptor agonists require clinical monitoring, and nausea, vomiting and other adverse effects should be reported to the prescribing team rather than managed at home. If a child is missing school for medical reasons, contact the school: schools have legal obligations to support pupils with medical needs, and that support does not need to be purchased. If a child shows signs of anxiety, perfectionism, low mood, food restriction or distress related to being measured or scored, discuss it with a clinician; a scored learning platform may not be appropriate. Screen time and sedentary time should be considered alongside the physical activity component of any weight-management plan. Consult a licensed clinician before starting or changing any treatment.
Date reviewed: 8 August 2026. Prices, quotations and terms were read from ixl.com, its help centre and its terms of service on that date and may change. Pricing observed on the family pricing page: 'Memberships start at only $9.95/month'; Single subject, Math (Pre-K to Calculus) or Language arts (Pre-K to 12), $9.95/mo; Combo package, Math plus Language arts, $15.95/mo; Core subjects, adding Science (K to Physics) and Social studies (K to 12), $19.95/mo. The help centre article 'Does a membership include all of my children or do I need to purchase multiple memberships?' states: 'There is no need to purchase more than one membership! You can purchase access for multiple children within your family membership. All children on the account will have their own individual profiles, complete with personalized analytics, awards and certificates unique to their accomplishments, and skills that adapt to each child's level. Pricing for a single-subject family membership starts at just $9.95/month or $79/year for one child. Each additional child costs $4/month or $40/year.' The article 'How does the SmartScore work?' states: 'When a student starts practicing a skill, the SmartScore starts at 0. As the student answers questions correctly, the SmartScore increases. If a question is answered incorrectly, the score decreases. However, the SmartScore is not just based on the percentage of questions correct. It is calculated using many factors, including the number of questions completed, question difficulty, and consistency… A skill is mastered when the SmartScore reaches 100, but the number of questions it takes to master a skill varies with every student… A score of 80 is proficient, and a score of 90 is considered excellent.' The article 'How do I cancel my membership?' sets out cancellation via the parent account, Subscription details, Cancel membership, Submit, and states 'You can cancel any time during your membership term, and your account will stay active until the end of that term… and you will not be charged again.' The terms of service at ixl.com/termsofservice state, in capitals, 'MEMBERSHIP SUBSCRIPTION RENEWAL FEES WILL BE AUTOMATICALLY CHARGED TO YOUR CARD ON FILE EACH SUBSCRIPTION PERIOD (MONTHLY OR YEARLY), UNTIL YOU CANCEL'; that 'Cancellation of Automatic Renewals. You may cancel your IXL membership at any time, and cancellation will be effective immediately. You will continue to have access to the program until the current billing period ends. We do not provide refunds or credits for any partially used membership periods'; that 'accounts may not be canceled until the end of the current term of the account'; and that '30-Day Satisfaction Guarantee. If you are not satisfied, a full refund of the purchase price can be requested within thirty (30) days of the Purchase Date. The thirty-day money back guarantee is limited to purchases made directly through IXL.com and does not apply to purchases made through any third' party. The terms also state that 'the amount billed each billing period may vary' and that IXL 'may change the fees and charges in effect, or add new fees'. Evidence claims are quoted from IXL's research page: 'ESSA Tier 1 evidence — Independent research from Johns Hopkins University has verified that IXL meets the ESSA Tier 1 standards for evidence-based efficacy'; 'ESSA Tier 1 report: IXL Math Efficacy — The Center for Research and Reform in Education at Johns Hopkins University conducted a randomized control trial (RCT) study meeting criteria for ESSA Tier 1 and WWC Without Reservations designations. The study found IXL Math students outgained control students by more than 10 points on the Renaissance Star Math assessment, with even higher gains for Hispanic, special education, ELL, and FARMS students'; 'IXL schools score as much as 15 percentile points higher in math and 17 percentile points higher in language arts on state assessments'; and that IXL 'has been awarded the Research-Based Design Product Certification from Digital Promise'. We have not independently obtained or appraised the underlying study report; we report IXL's characterisation of it and note that the percentile-point figures describe a comparison between schools rather than a randomised result. Company claims of scale observed on the pricing page: 'Over 18 million students use IXL', '200 billion questions answered and counting', 'Trusted by over 1,000,000 teachers', '20,000+ K‑12 skills', '1,300+ video tutorials' and '120+ games'; the Katalys programme description supplied to us says 'over 15 million students', which appears out of date relative to the site.

Trustpilot figures were read from the ixl.com profile on 8 August 2026: 1.1 out of 5 from 597 reviews, with the profile shown as unclaimed; because the profile is unclaimed and reviews are unsolicited, that distribution is self-selected and is not a measure of learning outcomes. Statements about ESSA evidence tiers and What Works Clearinghouse ratings describe the public frameworks and are not claims by IXL.
