A multidimensional selection battery was designed to predict a variety of criteria important in the selection of child care workers. The battery assesses constructs related to honesty, violence, substance abuse, emotional stability and safety. A series of studies were used to test the validity of the selection battery. Scores on the test battery were compared with those from three alternative selection procedures to define the measured constructs. Three additional studies show the relation of scores on the selection battery and the behavior of child care workers. The test battery was correlated with the job performance of child care workers and identified adults convicted for sexual offenses against minors.
