Research-based professional development opportunities for early childhood home visitors are valuable to the Early Head Start-Home-Based Option (EHS-HBO) and to the home visiting field broadly to strengthen effective practice. We explored EHS-HBO home visitors’ (N = 5) perspectives on effective practice through a professional development activity that included viewing videos of their own practice, analyzing the video and assessment data of their practice and parent–child interactions, and reflection. A convergent mixed methods multiple-case study was used. A variety of skills were noted within each  case as indicators of effective practice, suggesting that a plethora of complex skills are needed to work with families. (author abstract)
