Parent-implemented interventions (PIIs) have recognition as a practical and evidence-based practice, allowing parents to extend therapeutic gains from clinical to natural settings. This literature review examines the evolution, benefits, and effectiveness of PIIs, particularly considering the increasing relevance of telehealth methods. The shift from professional-led to parent-implemented intervention emphasizes empowering parents as co-educators, enabling continuous and consistent practice of intervention strategies in a child’s daily environment. The review highlights that PII not only improves children’s social skills, communication abilities, and adaptive behaviors but also enhances parental well-being by reducing stress and increasing confidence. The collaborative relationship between therapists and parents, combined with structured coaching and feedback, supports positive changes in parent–child interactions and family dynamics. However, challenges such as ensuring intervention fidelity, adapting to different cultural contexts, and maintaining long-term benefits post-intervention remain. Addressing these challenges involves tailored training for parents, ongoing support, and developing flexible intervention models that accommodate varying family needs and preferences. This review underscores the importance of integrating PII into broader autism intervention strategies to promote development for children with autism and their families.
