Objectives The DAKA model (Developmental Assessment Key Approach) addresses the complexity of autism through a biopsychosocial and clinically specialized lens, providing timely support to families in low-resource settings. It integrates early detection, evaluation, diagnosis, intervention, caregiver training, and the strengthening of support networks through a flexible, evidence-based system that combines digital and in-person modalities.Methods From 2021 to 2025, a mixed-methods approach was implemented, combining quantitative and qualitative user satisfaction data. The COVID-19 pandemic prompted the incorporation of telematic tools such as Zoom, enabling continuity of care and expanded territorial reach. Tools such as QChat and FUNCAS were used for early detection, while diagnostic assessments and therapeutic interventions included strategies like Relationship Development Intervention (RDI) and online caregiver training.Results A total of 243 early detection processes, 118 diagnostic evaluations, and 16 therapeutic support processes were recorded. Four complementary programs—family training, intersectoral capacity development, family accompaniment, and a volunteer-based respite care system—showed high user satisfaction and improved access in underserved areas.Conclusions DAKA has proven to be an effective and scalable strategy for low- and middle-income countries. The telematic approach, initially adopted in response to the pandemic, has demonstrated high impact in terms of sustainability and replicability of the model across diverse contexts.
