The period from 1977 to 1987 witnessed a decisive shift toward developmentally informed practice and rights-respecting reform in juvenile justice, with a growing emphasis on deinstitutionalization, diversion, and community-based treatment. Empirical inquiries began to illuminate juveniles’ capacities to understand legal rights, prompting age-appropriate advisement and procedural safeguards. The era also foregrounded gender-responsive policy and equity concerns, challenging punitive approaches that treated girls as a peripheral issue within the juvenile system alongside broader demands for more holistic care and rehabilitation.
