In juvenile dependency proceedings, the protection of children depends upon the collaboration between professionals in the child welfare and court systems. Since there is little empirical research on such collaborations, this exploratory study sought to identify factors associated with the difficulties encountered in these professional relationships through an analysis of case records. The data were extracted from 111 cases in seven Northern California counties. Using a logistic regression it was found that the short tenure of court professionals is significantly associated with the difficulties of fostering inter-professional collaboration. The implications for future practice and research are identified.
