This report describes the implementation and early impacts of the Washington State Integrated Basic Education and Skills Training (I-BEST) program at three colleges: Bellingham Technical College, Everett Community College, and Whatcom Community College. I-BEST is a nationally known program that aims to increase access to and completion of college-level occupational training in a variety of in-demand occupational areas. Its signature feature is team teaching by a basic skills instructor and an occupational instructor during at least 50 percent of occupational training class time. The three colleges operated I-BEST programs in one or more occupational areas including automotive, electrical, office skills, nursing, precision machining, and welding. Using a rigorous research design, the study found that the I-BEST programs at the three colleges significantly increased participation in college level courses, number of credits earned and credential attainment.
