Sri Lanka has a high level of political commitment for SDGs and a growing commitment to evaluation, hence operationalizing SDG architecture and accountabilities to ensure vertical and horizontal coordination across sectors and agencies is vital. National Policy and Strategy under the Sustainable Development Act guides implementation and coordination for the SDGs. A roadmap to achieve SDGs is under preparation and when finalized is expected to stimulate the demand for evaluation to assist in improving evidence-based decision-making. Lack of coordination and clarity in the roles of stakeholders involved in achieving the 2030 Agenda has resulted in difficulties in identifying and bridging the gaps for evaluation of SDGs. The Sustainable Development Council (SDC) as a coordinating body with a stronger leadership role would help to reduce the ambiguity in the roles and interlinkages between many partners and mechanisms involved in implementation of the 2030 Agenda. It is also expected to more clearly define the role of evaluation towards the progress on sustainable development. Sri Lanka Parliamentarians Forum for Evaluation orient members of parliament and decision makers at all levels to use evidence from evaluation for decision making.
