NCEO Reports: The Relationship between Student Placement and AA-AAAS Participation Rates (#439)


This report presents the findings of a study that looked at the relationship between states’ percentage of students participating in the alternate assessment based on alternate academic achievement standards (AA-AAAS) and the percentage of students in more restrictive learning environments. The 2015 reauthorization of the Elementary and Secondary Education Act (ESEA), known as the Every Student Succeeds Act (ESSA), placed a 1% cap for states on student participation in the AA-AAAS. This meant that states, districts, and individualized education program (IEP) teams need to carefully consider which students should be included in these assessments. Data used in this analysis were for 2018-19. This study found that states with higher percentages of students in more restrictive environments tended to have higher percentages of students participating in the AA-AAAS for both mathematics and reading.
