This article presents a comprehensive assessment of the PEP integrated within ECCD centre programmes in Bhutan. Drawing on data from a nationwide survey of 514 ECCD facilitators, complemented by qualitative insights from field observations and stakeholder interviews, the study examines implementation patterns, content relevance, observed impacts and persistent challenges. Findings indicate that 85.4 per cent of centres conduct parenting sessions regularly, demonstrating strong institutional commitment to parent-focused engagement. However, 91.2 per cent of centres have never delivered the full 16-session programme, with key barriers including lengthy sessions, irregular scheduling and parental socio-economic constraints. Programme content was rated as highly relevant, culturally sensitive and accessible by nearly 89 per cent of facilitators. Observable positive behavioural outcomes among participating families included improved hygiene and sanitation practices (64.9 per cent), enhanced nutrition (62.9 per cent), better parent–child communication (61.7 per cent), and a notable reduction in corporal punishment (27 per cent). The study concludes that while the programme represents a strategically significant and culturally responsive initiative, its full potential remains unrealised due to structural misalignments between curriculum design and the lived realities of families. Recommendations include curriculum adaptation into flexible modular formats, scheduling adjustments, strengthened facilitator support and robust monitoring systems.
