An assessment of the impact of Missouri's Workforce Incentive Project (WIN) on workforce development and child care quality. Using data already collected as part of the 4-year evaluation of the WIN program, this project extends the data analyses longitudinally for comparison between 503 participants of WIN and 376 non-participants who were followed over two years at 4-month intervals. Measures include turnover, professional development, and child care quality. The study informs policy and program choices about individual and program characteristics that motivate child care providers to attain additional education and training, and the efficacy of cash incentives for increasing workforce development and child care program quality.
