Dont such caps interfere with IEP decisions?
No. The policies on including students with disabilities in assessment and accountability systems do not affect the IEP teams role in making specific individual decisions about how to best address the needs of children with disabilities. The policies do not restrict the number of students who can participate in an alternate assessment. Instead, the policy restricts, solely for purposes of calculating AYP for school accountability, the number of scores that can be counted as proficient or advanced based on alternate achievement standards on alternate assessments.
