This brief describes a pilot of the BTS Collaborative approach with family child care networks and other organizations that support HBCC providers. The pilot aim focused on improving care for toddlers in mixed-age groups in HBCC. Participating teams, consisting of agency staff and providers, tested change concepts around technical assistance (i.e. coaching, home visiting, mentoring) as well as facilitation of peer-to-peer sharing among providers. Quality improvement data from the pilot indicated that teams across the Collaborative made improvements to agency staff practices and that providers affiliated with participating organizations increased their discussion, sharing, and engagement around trying new approaches to meeting the needs of toddlers in their programs. Because the pilot focused on an area of practice in early care and education where there is limited evidence for best practice, there was a strong emphasis on innovation. (author abstract)
