Longtime AEPS users will be familiar with much of the content and processes in this new third edition. The foundational model shaping AEPS-3 remains unchanged: AEPS-3 is still a linked system that directly connects assessment to goal development to intervention/teaching and progress monitoring. While test items have been revised and reorganized into one level instead of two, and two new developmental areas (literacy and math) have been added, the test remains an authentic, observational assessment with 3-point scoring and a criterion for each item.
