WWC Quick Review of the Article "The Negative Impacts of Starting Middle School in Sixth Grade"
What Works Clearinghouse
"The Negative Impacts of Starting Middle School in Sixth Grade" examined whether placing sixth graders in middle schools rather than elementary schools affects their behavior and academic performance. The What Works Clearinghouse (WWC) has reservations about the results because they may be affected by differences between the research groups that were not controlled for in the analysis. Strengths recognized by WWC include: Used statistical procedures to match similar middle and elementary schools. The following cautions were identified. Despite statistical matching, there were still some differences in the characteristics of the two groups of schools. For example, middle schools were in larger districts and had fewer economically disadvantaged students. The study authors used statistical techniques to adjust for these differences. However, differences in district policies, characteristics of the student body, and other factors not controlled for in the analysis may affect the results.
