This document is one of eight reports prepared to support the development of a new learning system, a development effort that is the first step in a major initiative undertaken by the Stupski Foundation. The Foundation endeavors to improve the life options of all students, especially underserved urban youth of color, whom we refer to as "Our Kids," by fundamentally redesigning the education system. The report was created collaboratively by researchers from McRel with guidance from officers of the Stupski Foundation. Its purpose is to provide a summary review of the literature contributing to the definition of "college readiness." The review aimed to identify the strategies, knowledge, behaviors, and skills needed before students are considered college ready upon graduation from high school. The definition of college readiness will provide members of a "Design Collaborative" team-- consisting of researchers, practitioners, parents, and students- with a knowledge base from existing literature to support their efforts to develop a learning system that will bring all students high levels of achievement and readiness for college. The literature review method is detailed in the appendix. (Contains 1 table, 4 figures, and 4 footnotes.) [This report is part of a larger set of reports prepared by McRel for the Stupski Foundation.]
