The test you need to make data-informed decisions

Better outcomes for children begin with the AEPS®‐3 Test—a reliable, efficient way to evaluate the skills children need to succeed in kindergarten. Spanning birth to 6 years in one seamless test, this criterion‐referenced assessment helps you develop meaningful learning goals and plan instruction and intervention that meets each child’s needs.

I like that [the test] is seamless between birth to six years. It will make it easier to move with the child as they age and help all involved with the child collaborate on the best plan of action.

Efficient & time-saving administration         

Avoid the unnecessary repetition of documenting and reassessing skills a child has already mastered. With its streamlined data collection system, AEPS-3 delivers what you need, when you need it. The relevant, high-quality data is easier to put into action for developing goals and measuring outcomes.


Shows progress for all kids   

You’ll see clearly what’s working and what’s not. Sensitive to changes in a child’s growth, no matter how gradual, the AEPS-3 Test captures even small increments of progress so you can recognize and appreciate gains and effectively support development.


Determine eligibility 

The AEPS-3 Test can be used as a valid source for helping you determine eligibility. The developers have established empirically validated cutoff scores that can be used for determining eligibility, and automated eligibility reports can be easily run in the AEPSi system.

Connect assessment with instruction

AEPS-3 streamlines the critical task of differentiating instruction. Assessment data is linked with friendly, activity-based teaching strategies in a multi-tiered (universal, focused, and specialized) curriculum that shows you what and how to teach children who are learning at different levels.

Discover the curriculum


I appreciate the expanded number of assessment and curriculum items on the low and high ends of age bands. When working with children with ASD who may have significant deficits in some areas and real strengths in others, it is often difficult to find developmentally appropriate assessments and curricula that meet their needs.
