He directed the Evaluation of the Content Literacy Continuum, a literacy-across-the-curriculum framework for high school reform, and the Enhanced Reading Opportunities Study, an evaluation of supplemental reading classes for ninth-graders. In addition, Corrin has participated in MDRC’s work on college-readiness programs in high schools, and codirects MDRC’s K-12 Education Policy Area. He formerly served as director of research, evaluation, and assessment for Evanston Township District 202 in Illinois and taught social studies at an alternative high school in the Charlotte-Mecklenburg public school system.
