PIL carried out a thematic evaluation of the ACF 2020–2024 programme in Lithuania, focusing on migration and LGBTQ+ issues. Applying a theory-based approach and mixed methods (stakeholder interviews, survey, project file review, case studies), the study showed ACF’s critical role in enabling NGOs to provide tailored services, run advocacy campaigns, and address legal and policy gaps in a challenging political environment. The findings provided the fund operator and donors with clear, evidence-based recommendations to strengthen sustainability, regional engagement, and impact measurement for future funding cycles.
