The current study evaluates the Workforce INcentive Project (WIN), a programmatic effort to increase child care workforce stability in center- and home-based child care providers via the provision of bi-annual cash incentives based on educational attainment. Five hundred and thirteen center-based teaching staff (304 WIN and 209 comparison) and 167 center directors (93 WIN and 74 comparison) from 179 state-licensed child care centers (99 WIN and 80 comparison) participated in the study reported. Survival analyses were conducted to compare turnover rates between the WIN group and the comparison group over a 20-month period. All analyses controlled for participant satisfaction with employment, location (i.e., urban, suburban, and rural), and, where appropriate, hourly wages. Although WIN participation was generally associated with lower rates of turnover in center-based staff, when position type, educational attainment, experience in the field, and hourly wages were considered (separately and together), WIN’s relationship with turnover varied widely for directors and teaching staff. Findings are discussed in terms of past research and future cash incentive programs. (author abstract)
