This report will provide the results of several cohorts from a large-scale validation study of Washington State’s Department of Children, Youth and Families child care Risk Assessment Licensing Decision Making Tiers System (RALDMTS). The validation involves two key components: 1) Validation of the measurement strategy used to determine the licensing decision making for child care centers and family child care homes; 2) Validation of the licensing system in juxtaposition to the program quality measures (ERS & CLASS) as part of their QRIS – Quality Rating and Improvement System utilized in Washington. The data set involves several cohorts drawn from licensing reviews in 2019 – 2020. The data reported in this report is from late 2019 through early 2020 and involved 385 sites. It was driven by the QRIS visiting and assessment schedule. (author abstract)
