No Child Left Behind / Adequate Yearly Progress
How Illinois Calculates AYP
AYP will be calculated once the report card data are submitted and approved by local superintendents and all of the assessment scores are available for the school. The assessment data should be considered final unless errors are identified or rescoring is requested.
A 95% confidence interval will be applied for all students and/or subgroups with less than 77.5% Meeting/Exceeding standards.
The following is how Safe Harbor is calculated:
- A minimum size of 45 students in the same subgroup for two years
in a row is necessary to apply safe harbor.
- If a subgroup does not meet the performance target in either subject,
- AND the same subgroup decreased by 10% the percentage of scores
that did not meet state standards from the previous year,
- AND the subgroup meet the other indicators (see below) for the subgroup.
- THEN Safe Harbor can be applied.
The Illini Equal Steps chart shows the progress students need to make annually to reach the goal of 100% proficient in reading and mathematics by 2013-2014.
