Publication Date: 2005-09-26

Synopsis:

Reports modeling results for several states of the effect of various sizes of minimum-n and confidence intervals on No Child Left Behind AYP determinations. Key findings include high percentages of special education students excluded by minimum-n sizes currently used by several states, and therefore the special education subgroup meeting AYP solely because of minimum-n rather than through performance.
