This brief, the fourth annual, describes Oregon’s early learning workforce in 2015. As of 2012, Oregon has had in place a system that allows it to answer policy-relevant questions about the early learning workforce employed in regulated child care and education facilities. This brief captures key characteristics of the 2015 workforce and compares them with those of the 2012 workforce. Annual reports enable the State to measure workforce turnover and provide decision makers with information critical for designing the training system. With access to four years of data, this study provides a new look at turnover and stability of the workforce.
