This report provides an updated review of state criteria and guidelines for participation in AAAAAS. We analyze state criteria for participation and factors not to use as the basis of decision making, as well as how states define students with the “most significant cognitive disabilities.” As the resources on state websites have increased, topics covered have expanded to include other information found in the criteria and guidelines: information for parents/guardians, English learner (EL) considerations, and exemptions from participation in the AA-AAAS.
