Absence of Conflict of Interest

The Campuzano et al. (2009) study summarized in this intervention report was prepared by staff of Mathematica Policy Research. Because the principal investigator for the WWC review of High School Math also is a Mathematica staff member, the study was rated by staff members from RAND and SRI. The report was then reviewed by the principal investigator, a WWC Quality Assurance reviewer, and an external peer reviewer.
