Overview: TIER has deep expertise in the areas of family support and home visiting programs and initiatives. For the past two decades, TIER has worked with national, state, and local program partners to evaluate existing home visiting programs, plan for new home visiting programs, and engage in home visiting system-building initiatives. TIER has strong ties with the Maternal, Infant, and Early Childhood Home Visiting (MIECHV) program, both locally and nationally, and has been the lead evaluator for the Massachusetts MIECHV program since its inception, including implementation studies, quasi-experimental studies, needs assessments, and participation in two Coordinated State Evaluations. TIER also conducted a longitudinal randomized controlled trial of Healthy Families Massachusetts (HFM), the largest home visiting program in Massachusetts, and continues to conduct applied mixed methods evaluation studies with HFM partners.
