This bulletin provides guidelines to Missouri educators concerning inclusion of students with disabilities in state and district-wide assessments of school achievement as required under Missouri's Outstanding Schools Act and the reauthorization of the federal Individuals with Disabilities Education Act of 1997. It stresses the greater focus on accountability for educational services provided to students with disabilities. The five questions and answers address the following topics: (1) reasons for requiring students with disabilities to participate in the Missouri Assessment Program (MAP) and district-wide assessments; (2) decisions of the individualized education program (IEP) team concerning a student's involvement in assessments; (3) assessments included in the MAP; (4) assessments that must be considered at the district level; and (5) factors that IEP teams need to consider in deciding about a student's participation and accommodation in assessment. An inset lists eligibility criteria for participation in MAP-A and a table lists accommodation codes for IEP students. (Contains references.) (DB)
