NCEO Brief: Guidance for Examining Disproportionality of Student Group Participation in Alternate Assessments (#18)


The purpose of this brief is to examine disproportionality with respect to student group participation in Alternate Assessments aligned with Alternate Academic Achievement Standards (AA-AAAS). It is a companion to the NCEO brief, Guidance for Examining District Alternate Assessment Participation Rates. This brief provides a more detailed examination and illustration of a particular issue, disproportionality. The companion brief outlined a broad framework and general principles to guide the examination of AA-AAAS participation rates, particularly in light of the challenge of small n-sizes and associated uncertainty. It begins by reviewing the framework with respect to its application to address disproportionality in participation in the alternate assessment aligned to alternate academic achievement standards. This is followed by an illustration of specific analytic steps, and concludes by providing guidance for further inquiry that links back to the guiding principles in the framework.
