A system you can trust

No other assessment and curriculum system is backed by more scientifically valid research than AEPS®-3. What’s behind the AEPS-3 system? More than 40 years of studies, led by early intervention visionary Dr. Diane Bricker and the Early Intervention Management and Research Group (EMRG). Thousands of hours of field testing. Valuable feedback from teachers, families, and other members of a child’s team.

The result: a linked system that takes you directly from reliable, valid, and highly sensitive assessment to custom-tailored teaching and intervention. The outcome: real progress for the individual child.

AEPS-3 Test scores that show change over time provide an accurate measure of actual changes in a child’s performance, making AEPS-3 a highly reliable tool. You can see exactly which new skills and behaviors children are learning—and which of your interventions have been most effective.

AEPS-3 Test items have been written to ensure consistent interpretation across observers. Research shows that AEPS Test results are stable across different observers and stable over time. That means your assessment team can be confident that different people will interpret test items similarly.



The AEPS-3 Test has been validated as an alternative to norm-referenced, standardized tests for purposes of eligibility determination. It’s been shown to do as well as or better than traditional measures at identifying young children who require special services and supports. Children’s scores on the AEPS-3 Test and their scores on other popular assessment instruments show similar patterns, which is another indicator of AEPS-3’s validity.


The research never stops

The Early Intervention Management and Research Group (EMRG), a non-profit mutual benefit corporation, leads the development and ongoing research for AEPS-3. Studies on AEPS-3 are currently being conducted in the United States, Canada, Spain, Kosovo, and more countries throughout the world. And we look to our users—the educators, families, and professionals using the system on a daily basis—to inform the future evolutions of AEPS. To participate in ongoing AEPS research, contact
