Sustainability is not a key component of policy evaluation, as it is more concerned with the long-term viability of a policy rather than its immediate impact.

Impact assessment serves multiple purposes, including determining the effectiveness of a policy, identifying unintended consequences, and assessing cost-effectiveness.

Policy evaluation often employs a mixed methods approach, combining quantitative and qualitative data to provide a comprehensive understanding of a policy's impact.

Policy evaluations face several challenges, including lack of data, political interference, and resource constraints.

Policy evaluation plays a crucial role in evidence-based policymaking by providing rigorous evidence, identifying areas for improvement, and informing policy decisions.

Formative evaluation is conducted during policy development to identify areas for improvement, while summative evaluation is conducted after implementation to assess overall impact.

Positive impacts are not a type of policy impact, as they are the desired outcomes of a policy.

Stakeholders play an important role in policy evaluation by providing input, participating in data collection and analysis, and reviewing and interpreting findings.

Policy evaluation promotes accountability and transparency by providing evidence on policy performance, identifying areas for improvement, and holding policymakers accountable.

Reduced government spending is not a direct benefit of policy evaluation, although it may be an indirect outcome of more effective and efficient policies.

Considering equity in policy evaluation is important to ensure that policies do not harm certain groups, promote social justice, and assess the distributional impacts of policies.

Policy evaluation contributes to policy learning and adaptation by providing evidence, identifying areas for improvement, and facilitating knowledge exchange.

Impact assessments face challenges such as lack of data, difficulty in isolating the impact of a single policy, and political interference.

Policy evaluation can improve the efficiency of public spending by identifying cost-ineffective policies, providing evidence on cost-effectiveness, and helping policymakers prioritize spending.

Ethics play a crucial role in policy evaluation to ensure fairness, protect participants' rights, and ensure the use of evaluations for the public good.
