The transition from high school to adulthood is challenging for many students, but particularly for students who hold membership in marginalized populations. College and career readiness (CCR) supports can help students with intellectual and developmental disabilities (IDD) and emotional and behavioral disorders (EBD) and those who have had interactions with the juvenile justice (JJ) system to find postsecondary success in a variety of areas, including employment, independent living, postsecondary education, leisure/social activities, and self-advocacy. CCR-focused consultation in the schools is a natural vehicle for improving transition planning, intervention implementation, and professional collaborations. This theme issue showcases partnerships and provides resources for practitioners, educators, and decision makers regarding CCR consultation approaches for youth with IDD, EBD, and JJ interactions.
