This session presents the ASCEND Fellowship, a DOE-funded program preparing school counselors to support students with disabilities. Grounded in the ASCA National Model and experiential learning, the program integrates coursework, a speaker series, and a summer bootcamp (ASCA, 2019, 2022; Kolb, 1984). Attendees will gain strategies for developing evaluation frameworks and applying mixed-methods data to assess counselor competency (Havlik et al., 2019).
