Does NCLB improve the achievement of students with disabilities? A regression discontinuity design. Journal of Research on Educational Effectiveness, 5 (1), 18–42.
The No Child Left Behind Act (NCLB) holds public schools accountable for the academic achievement of student subgroups that are larger than the state minimum-subgroup-size threshold. In 2004, California added students with disabilities to the NCLB subgroup categories. Using a regression discontinuity design, this study compared the academic achievement of students-with-disabilities subgroups that were just above the minimum-subgroup-size threshold to those just below the threshold. The results showed no effects of holding schools and teachers accountable for the achievement of students with disabilities after controlling for student performance and school characteristics of the previous academic year. Policy implications are discussed.
