This research brief describes the professional development (PD) experiences of Head Start staff (program directors, center directors, teachers, and other staff), using nationally representative data from the spring 2017 round of the Head Start Family and Child Experiences Survey 2014-2018 (FACES 2014). First we describe the landscape of PD for a variety of staff in Head Start. Next, we describe two specific types of PD that support classroom quality improvements: (1) coaching; and (2) assessment and curriculum support. We also examine whether selected PD supports vary by program agency type, program size, teacher experience, and teacher education.
