Ronald Hughes, Judith Rycus, and their colleagues have produced a seminal review of differential response (DR) programs implemented across the nation. Their review questions nearly every aspect of the DR movement, beginning with the concept on which all DR programs are based and ending with serious concerns about the quality of evaluations conducted to date. Given current support for DR initiatives and wide variation of existing DR models, not all in the social sciences will agree with their conclusions. Nevertheless, this review represents the type of analysis critical to advancing practice in the field. Although many issues are raised in the Hughes et al. review, our response focuses on four critical points, which we believe represent the core problems identified. These include the concept that serves as the foundation for the DR movement, the role of assessments, and the primary problems with evaluations conducted to date.
