Kurlaender, Michal & Howell, Jessica. (2012). Collegiate Remediation: A Review of the Causes and Consequences. College Board Advocacy & Policy Center.
This literature brief from researchers at the College Board summarizes their review of the research around developmental education.  The report includes national remediation statistics pulled from the literature.  The researchers cite the lack of conclusive evidence around the impact of remediation on subsequent student success and find that the two strongest areas with most support for reducing the need for remediation are strong high school preparation and alignment of K-12 education and college education systems.

The Developmental Education Initiative. (2010). State Policy Framework & Strategy. Achieving the Dream.
This report outlines findings and strategies developed out of the Achieving the Dream Initiative and the subsequent Developmental Education Initiative to improve success for students.  Five categories of strategic policy priorities are discussed; reducing the need for developmental education through K-12 and postsecondary curricular alignment, using data for measuring institutional outcomes and performance, using accurate assessment strategies to determine students’ college readiness, and redesigning the developmental education system, and remove barriers to test and scale innovative interventions that work.
