From the RAND Corporation website:  "In education, practitioners are increasingly looking for strategies to bring data and evidence into decisionmaking and to roll out programs in intentional ways that allow for ongoing improvement. This toolkit acts as a guide to improvement strategies for teams of practitioners at colleges, providing them with the knowledge and tools they need to carry out rapid cycles of data-driven improvement. 

The toolkit applies improvement approaches to corequisite remediation, a common initiative being adopted by colleges. Corequisite remediation shifts the way that students are supported in college by allowing them to directly enter a college-level course and receive additional academic support during that same semester to address the challenges they face with basic math, reading, or writing concepts (rather than requiring students to complete a series of developmental education courses)."
