In 2006, six community and technical colleges in Washington State joined the innovative national reform initiative called Achieving the Dream (ATD). This report describes the progress each college made in implementing ATD's "culture of evidence" principles for institutional improvement, examines strategies implemented by the colleges to improve student success, and charts trends in student outcomes in the period before and after the colleges began their participation. All but one of the colleges made at least some progress in building a culture of evidence. Four of the colleges made significant systemic changes to programs, services, and instructional practices. Yet, most of their work was focused on helping students upon their entry to college. We argue that the Washington ATD colleges and others pursuing similar goals should also examine how they can help students better enter and complete a program of study if they hope to improve student completion and success. Appended are: (1) Framework for Measuring College Progress in Implementing the ATD Culture of Evidence Model; (2) Survey Results on Data Use by Faculty and Administrators at the Washington ATD Colleges; (3) Additional Student Outcome Trends at the Washington ATD Colleges; and (4) Average Student Outcome Changes at Individual Washington ATD Colleges. (Contains 25 figures, 22 tables, 2 boxes, and 15 footnotes.) [This report was written with Oscar Cerna, Dan Cullinan, and Phoebe Richman.]
