ICYMI: In March 2025, we updated the names of IXL’s diagnostics to better reflect the capabilities of our assessments! Learn more about the changes to IXL’s diagnostics here.

For the 2025-26 school year, IXL is giving schools and districts even more flexibility to assess student needs, with the ability to use one or both of IXL’s powerful diagnostics. Customize your diagnostic tool across different subjects and grade levels, depending on your unique needs and goals.

Introducing your choices:

• IXL LevelUp™ Diagnostic for PreK-12 math and ELA
• IXL Flex Diagnostic for PreK-12 math and ELA

Both assessments empower educators with immediate, personalized action plans for every student, and can be flexibly used in Benchmark and Real-Time modes.

If you answered… 

• Mostly A’s: IXL LevelUp Diagnostic
• Mostly B’s: IXL Flex Diagnostic
• A mix of A’s and B’s: Both diagnostics 

If you answered mostly A’s… 

Then the IXL LevelUp™ Diagnostic is your match! 

You’re looking for a powerful, standards-aligned benchmarking tool that delivers valid, reliable results quickly. 

Here’s what sets it apart:

• Captures true benchmark data: The LevelUp Diagnostic captures student performance based solely on their responses in the diagnostic on test day.
• Measures state standards performance with precision: Get detailed, state-specific reporting on individual standards, helping you understand exactly where students stand.
• Maximizes classroom time: With built-in time limits for each question and the overall benchmark assessment, the LevelUp Diagnostic helps you maximize instructional time. 
• Supports Spanish-speakers: Students can access Spanish language and audio support in the math assessment. 
• Flags students at risk of reading difficulties: The LevelUp Reading Benchmark identifies students who may be at risk of reading difficulties including dyslexia, so that they may be evaluated further by a specialist.

If you answered mostly B’s… 

Then the IXL Flex Diagnostic is right for you! 

You value a student-centered, engaging experience and believe that student evaluation can be informed by multiple sources, such as skill practice. 

Here’s why educators love it:

• Engages students authentically: Students can skip questions they feel are truly out of reach, receive encouraging feedback, and are motivated to learn. 
• Gives students a head start on assessment time: Skill practice and student work in Real-Time mode feed into the Flex Diagnostic, shortening the time it takes to pinpoint diagnostic levels. 
• Compares performance nationally: With national norm data available for PreK-12 math and ELA, the Flex Diagnostic allows you to evaluate student performance on a national scale.

If you answered a mix of both A’s and B’s… 

Why not leverage both? 

For the 2025-26 school year, administrators have the flexibility to mix and match the IXL LevelUp Diagnostic and the IXL Flex Diagnostic in a way that best fits their needs. You can select your preferred diagnostic assessment for each subject and grade band.
