When it comes to math instruction in special education, getting a clear picture of what your students actually know is everything. It’s not just about finding gaps — it’s about understanding how they think, where they get stuck, and how to build meaningful growth from there.
That’s where math screeners and diagnostics come in. They help teachers identify strengths, skill gaps, and instructional needs so we can create IEP goals and intervention plans that truly match each learner.
Below, you’ll find some of the most trusted and teacher-approved math screeners and diagnostics for special education. Each one offers something a little different — from universal number sense screeners to in-depth diagnostic interviews that dig deep into student understanding.
Math Screeners
Screeners give you a quick, reliable snapshot of where students are performing compared to grade-level expectations. They’re ideal for identifying students who may need further assessment or intervention.
MAP Growth
One of the most widely used universal screeners, MAP Growth provides adaptive assessments that adjust to each student’s performance in real time. It gives clear data on growth, readiness, and instructional level — and it’s especially useful for tracking progress throughout the school year.
Star Math
Star Math is another popular screener for identifying strengths and weaknesses in core math areas. It’s computer-adaptive, short, and easy to administer, making it a great option for frequent progress monitoring.
Forefront Number Sense Screener
This universal screener focuses on number sense and early math understanding. It’s straightforward, data-driven, and works beautifully with Bridges Intervention (which many teachers love pairing it with). Perfect for early elementary or foundational skill checks.
Delta Math Readiness Assessments
Delta Math offers free, skill-based readiness assessments that break math down by specific standards and grade levels. The reports are easy to read and help you pinpoint exactly which areas to target next. A fantastic option for schools or teachers on a budget.
Math Diagnostics
Diagnostics go deeper than screeners — they help you uncover why a student struggles. These tools analyze mathematical reasoning, number sense, computation, and conceptual understanding in more detail.
ALEKS (by McGraw Hill)
ALEKS offers comprehensive, adaptive diagnostics that identify what each student knows and what they’re ready to learn next. It’s a bit of an investment, but the data you get is worth it — detailed, thorough, and incredibly accurate. Teachers often appreciate how well it aligns with IEP goal-setting and individualized instruction.
WRAT5 (Wide Range Achievement Test, 5th Edition)
The WRAT5 is a standardized diagnostic tool that measures math computation and problem-solving skills. It’s often used for formal evaluations or progress tracking over time and provides reliable percentile and standard scores.
AVMR (Add+VantageMR)
This diagnostic interview dives deep into how students think about numbers and operations. It’s not just about right or wrong answers — it’s about uncovering the strategies (and misconceptions) behind them. AVMR is ideal for teachers who want to truly understand each student’s mathematical thinking.
Math Diagnostic Interview
These structured interviews help teachers explore how students approach mathematical problems conceptually. They can be used to confirm screener results or guide IEP goal writing. The insights you gain often shape more targeted instruction and interventions.
Georgia Numeracy Project
Developed by the Georgia Department of Education, this free tool offers comprehensive number sense screeners and diagnostics for teachers to administer. It’s a great starting point for those looking for quality assessments without the cost.
Support for PreK-6th Grade — Inside The Intentional IEP
If you’re looking for ready-to-use math screeners and diagnostics that align directly with academic IEP goals, The Intentional IEP has you covered. Inside the System, you’ll find preK–6th grade Screeners for every academic area, designed specifically for special education teachers, plus our exclusive Screener Generator.
Each resource was built to save you time, reduce paperwork stress, and give you clear, functional data that connects directly to your IEP goals.

Whether you’re starting a new school year or reassessing mid-year progress, math screeners and diagnostics can make all the difference in identifying your students’ true needs. The right tools give you the clarity and confidence to write measurable goals, select targeted interventions, and celebrate every bit of progress along the way.
Remember: the goal isn’t perfection. It’s progress. And these tools help you see it clearly, one math skill at a time.
Writing the IEP is only one part of managing it. The Intentional IEP System helps special education teachers manage the work before, during, and after the meeting—from baselines and goals to timelines, implementation, progress monitoring, and everything in between. Instead of piecing together another resource every time something comes up, you’ll have one educator-led system designed to help you know what to do, have what you need, and know what’s next.
