This study addresses organizational factors associated with child welfare workers' data use in their day-to-day work. Survey data from 237 respondents were analyzed using logistic regression. Familiarity with data and supervisor support were significant predictors of child welfare workers' data use. Findings highlight the value of child welfare organizations (a) facilitating workers' familiarity with child welfare data and data use and (b) training or educating supervisors so that they can support workers' use of data.
