Introducing the IXL Diagnostic!

August 31, 2017


At Home, In the Classroom, For Admins

Big news: we’ve got a new classroom essential that’s going to make your back to school experience even better! The IXL Diagnostic is the first of its kind, delivering student insights that are always up to date. It also offers personalized recommendations that tell you exactly how to target knowledge gaps and help students progress. It’s a game-changing resource for both teachers and students!

Insights that are always up to date

With the IXL Diagnostic, you always have a complete and accurate portrait of students’ knowledge. While students work through regular IXL skill practice and answer just a handful of diagnostic questions a week, the IXL Diagnostic works in the background and continuously updates their results.

Unique action plans for each learner

The IXL Diagnostic provides specific skill recommendations for individual students and small groups based on their diagnostic results. These recommendations target their needs at the perfect difficulty level and are drawn from IXL’s math skills, so they’re available with just one click!

An empowering student experience

Unlike traditional assessments, the IXL Diagnostic is designed to empower and motivate your students. Their results and recommendations are available anytime they want to see where they’re excelling and what they can do to improve.

How it works

The IXL Diagnostic adapts to students as they answer questions in order to hone in on their level of knowledge. It offers an engaging and informal experience where students can start and stop diagnosing at any time.

There’s lots to explore with the IXL Diagnostic! See it for yourself at and check out the video below to learn more:

Are there plans on expanding this tool to be used with the ELA skills in the future?


The IXL Team September 6, 2017 at 10:13 am

Hi Rebecca–We’re currently focused on making the IXL Diagnostic experience the best it can be for math, and in the future may expand this feature to other subjects.


Susan Hopper September 25, 2017 at 7:01 pm

I would love to see the diagnostic features expanded to ELA!


Charles Leitzell September 8, 2017 at 7:58 am

Is the diagnostic tool available to students who are using the app? If not, do you have an app update coming?


The IXL Team September 8, 2017 at 10:24 am

Hi Charles–Currently the IXL Diagnostic is available for math in the U.S. edition, and only on the IXL website. We’re currently focused on making the IXL Diagnostic experience the best it can be, and in the future may expand this feature to other platforms. In the meantime, you can access the diagnostic on a mobile device using your web browser.

Can you please explain the scores on the diagnostic display? Also, I am using IXL with students who have deficits in math. Will the diagnostic present problems for students to solve that are below their current grade? Thank you!


The IXL Team September 8, 2017 at 5:05 pm

Hi there–The diagnostic level indicates a student’s working grade level. (For example, a level of 500 indicates readiness to work on fifth grade level skills.) All student levels start as a range, but those ranges will narrow down as the student continues to diagnose. When the Diagnostic has enough information to pinpoint the student’s level, it will appear as a single number. The Diagnostic is a great tool to use with students of all math levels; students will frequently be given a choice between one of two questions to answer and they always have the option of selecting “I don’t know this yet.” The IXL Diagnostic is adaptive, so as students answer questions, it recalibrates to find the best question to ask next in order to hone in on their level of knowledge. If you have any other questions about the Diagnostic, we’d be happy to help! Contact us anytime at

I love IXL


Elizabeth Bostic September 12, 2017 at 2:41 pm

Do you have a percentile showing what scores would make the students fall under the 21st percentile for the purposes of RTI and using this diagnostic as a universal screener?


The IXL Team September 12, 2017 at 4:17 pm

Hi Elizabeth–Since the IXL Diagnostic is not primarily intended to be used to compare students to other students at one point in time, we don’t have percentiles like what you describe. Instead, the Diagnostic was designed to help identify individual students’ current levels of understanding, strengths, weaknesses, and pinpoint exactly what they are ready to learn next.


Sara M September 24, 2017 at 5:58 pm

One of our teachers shared that the Diagnostic took her class over 2 hours to complete (5th graders). Is this common? Can the Diagnostic be done in parts or must it be done all in one sitting? Any info you can share would be helpful!


The IXL Team September 25, 2017 at 2:55 pm

Hi Sarah–Great question! Most students will need 60-90 questions to get complete diagnostic results—and this definitely doesn’t have to be done in one sitting. The number of questions needed will vary based on each student’s performance and existing practice results. After that, about 5-10 diagnostic questions per week will keep the Diagnostic fully up-to-date (and that way, they won’t need to start over with an extended diagnostic session in the future). If you have any other questions about the Diagnostic, we’d be happy to chat–just contact us at (855) 255-8800 or


Killian W. September 25, 2017 at 11:08 am

The diagnosis is AWESOME it has been helping me with math A LOT!!! It give you all new recommendations that also help me alot!! Only one question though, is narrowing down in diagnosis a good thing?


The IXL Team September 25, 2017 at 3:08 pm

That’s great, Killian! We’re glad to hear you’ve been enjoying the Diagnostic. Narrowing down is a good thing–it means the Diagnostic is getting closer to pinpointing your level and giving you more relevant recommendations.

Have heard many positive comments about the New Diagnostic feature. Some questions (from a 6th grade math teacher):
(1) does it provide only a Diagnostic “snapshot” of where the student is at present, or is there some report where I can see a student’s growth over a period of time, etc. (similar to the regular IXL reports that show unit completion, % score, # of questions answered correctly and incorrectly, etc.)?;
(2) I assign various IXL units each week (for example, units within the 6th grade Common Core curriculum) – will these be “taken into account” by the Diagnostic tool?;
(3) should I continue to assign IXL units each week, as opposed to simply having students work on the Diagnostic each week – or should I assign both?
Thank you.


The IXL Team September 26, 2017 at 11:26 am

Hi Scott–We’re excited that you’ve heard so many positive comments about the Diagnostic! The IXL Diagnostic is meant to inform teachers and students about their current level of understanding, so it will always be up to date. While there isn’t a Diagnostic report like what you describe, teachers can print out students’ diagnostic stats (which show current levels and skill recommendations) periodically to chart their development over time. They can also check off completed skill recommendations on the printouts as a record of the progress students have made.

Yes, IXL’s diagnostic algorithm tracks students’ practice and performance on IXL and takes that information into account when generating questions on the Diagnostic, calculating their diagnostic levels, and recommending “From the diagnostic arena” skills!

The Diagnostic can be used in a variety of ways in your classroom. We generally encourage teachers to combine regular IXL assignments with Diagnostic practice. By both regularly practicing on IXL and by regularly diagnosing, students will have a chance to master skills that will help them grow and receive their most current levels. Once students have received an overall diagnostic level and levels in each of the six strands, we recommend that they answer 5-10 diagnostic questions per week to keep their diagnostic stats up to date.

If you’d like to chat more about how to best use the Diagnostic with your students, we’d be happy to help! Just contact us at (855) 255-8800 or


Scott A. September 27, 2017 at 6:53 am

Thanks IXL for the reply.
(1) I would ask that you create a report capability for the Diagnostics, so I can see (and print) a list of the kids in my class and see their diagnostic levels for each of the strands. With 75 students this year, I want the single-page listing capability, so that I can easily see their status (and not have to flip through all those kids).
(2) I’d also like the ability to see, again in summary fashion, the Diagnostic score(s) of my students at various points in time. So, a report that shows me what their initial Diagnostic score/level was, and then another column showing me their current score/level (some weeks or months later), so I can see how they are progressing. Again, in summary fashion, so I can get a quick read on my 75 students and then easily identify those who I should drill down further on.


The IXL Team September 27, 2017 at 9:53 am

Thanks for your feedback, Scott! The IXL Diagnostic is a new feature, so our development team is actively working on refining it further. We’ll pass your requests along to them.


Stephen Burgess October 9, 2017 at 11:52 am

So where is my diagnostic option. I paid for a yearly family membership? Why don’t I get access?


The IXL Team October 9, 2017 at 3:46 pm

Hi Stephen–The IXL Diagnostic is currently available for math in our U.S. edition, though we may expand to other subjects and editions in the future. If you are subscribed to math in our U.S. edition and are having trouble accessing the diagnostic, we’d be happy to help–just contact us at


Scott A. October 20, 2017 at 8:59 am

Hello IXL Team – My students have worked on the Diagnostic and have skill “circles,” not oblong shapes. When they continue to work on the Diagnostic, they can work on Recommended Skills (RS). My question is this: When they work on a Recommended Skill, how far do they have to go (in terms of % score achieved) to improve their circle bubble score level? In other words, must they work to 100% on the skill? 90%? Is there a score below which their bubble score would actually decrease?
I need to understand this to be able to tell my students what they should do on the RS to improve their existing bubble score level. Thanks.


The IXL Team October 20, 2017 at 4:24 pm

Hi Scott–It’s great that you’re utilizing the recommended skills after your students’ diagnostic practice! Getting a score of 90 or higher on a recommended skill will have the maximum impact on their diagnostic score, and we do also recommend that students answer 5-10 diagnostic questions per week to keep the Diagnostic updated. When you see a single number as a student’s diagnostic score, that indicates the student’s working grade level. For example, a level of 500 indicates readiness to work on fifth grade level skills. Whereas, when their score appears as a range (for example, 400-600), it means that the Diagnostic does not yet have enough information to pinpoint a student’s level. If you have any other questions about how best to use the Diagnostic with your students, we’d be happy to help! Feel free to get in touch at or (855) 255-8800.

ozlem November 26, 2017 at 8:13 pm

Hi, we have parent subscription to europe curriculum. Do you plan to implement diagnostic for europe soon? It looks really great and what I need to support him, I can switch the country to US but he will be devastated to loose all of his awards 🙂


The IXL Team November 27, 2017 at 10:34 am

Hi Ozlem–We’re currently focused on making the IXL Diagnostic experience the best it can be for our U.S edition but may expand this feature to other editions in the future. Although your son’s awards won’t transfer to the U.S. edition, his awards and progress will be saved in your Europe account, should you decide to return to the Europe edition later. If you have any other questions about switching editions or about memberships in general, we’d be happy to help–just contact us at

Eskes January 6, 2018 at 8:08 am

Hi- My 6th grade son is using diagnostic IXL to work at his own pace at school and at home. He has been working on calculus problems, continues to make progress and enjoys these problems the most. My question is that this does not seem grade level so is he really doing calculus or is just a beginning level of what he will be doing when he is older? How accurate is the diagnostic in recommending skills and level?


The IXL Team January 8, 2018 at 10:35 am

Hi Eskes–As students work on the Continuous Diagnostic, it may uncover knowledge gaps or areas for extra practice that are below grade level, so your son may encounter skills that are designed to build his knowledge. We’d be happy to chat with you more about IXL’s Continuous Diagnostic and answer any questions you may have! Please contact us at or (855) 255-8800.


Michelle DeFosset January 8, 2018 at 11:05 am

I love IXL and we are using it as a tool for our Math Lab students. Can you possibly tell me how the Diagnostic Level is determined. It seems that a few of my students have a lower diagnostic score then they did before. Does that make sense? I wasn’t have them work in the Diagnostic arena weekly…is that why they are scoring at a lower grade level? For example: The first time they scored a 680 the second time they scored a 620. Should I have them be doing anything in particular?


The IXL Team January 9, 2018 at 11:10 am

HI Michelle–We’re glad to hear you love IXL and that you’ve found it helpful in your math lab! After students’ diagnostic level has been pinpointed to a single number, we do recommend that they complete about 5-10 diagnostic questions per week to keep the Continuous Diagnostic fully up-to-date. Regular IXL practice is also taken into account in diagnostic results, so if your students have had any trouble with certain skills it may affect their Diagnostic level. If you have any other questions about the Continuous Diagnostic and the best ways to use it with your students, we’d be happy to help! Just contact us at
