Navigating the complexities of impact evaluation is essential for any research organization committed to evidence-based growth. While the goal is to measure long-term change, several hurdles often complicate the process.
Some common challenges in conducting impact evaluation include: #
- Attribution and Causality Issues
- One of the biggest challenges is isolating the actual effect of an intervention. External factors—such as economic changes or parallel programs—can influence outcomes, making it difficult to establish a clear counterfactual. Methods like Randomized Controlled Trials (RCTs) help address this, but they are often technically demanding and resource-intensive.
- Data Collection Challenges in the Field
- Collecting reliable data in real-world settings is rarely straightforward. Issues such as maintaining data quality in remote locations, dealing with incomplete records, and managing high turnover among field staff can all affect the credibility of findings.
- Resource Constraints in Evaluation
- Limited budgets and capacity often force organizations to make trade-offs. Investing in strong M&E systems can compete with funding for program delivery, making it difficult to maintain both quality implementation and rigorous evaluation.
- Stakeholder Engagement Barriers
- Engaging stakeholders is not always easy. Internal teams may resist evaluation due to fear of unfavorable results, while donors may prioritize quick scaling over careful assessment. These tensions can affect both participation and objectivity.
- Managing Evaluation Timelines and Costs
- Timing is critical. Evaluations need to align with program cycles so that findings remain relevant. Poorly managed timelines or budget overruns can lead to rushed analysis or insights that arrive too late to inform decisions.
By addressing these challenges thoughtfully, organizations can turn impact evaluation into a meaningful process that supports learning, accountability, and continuous improvement.

Impact Evaluation of Development Programs: Challenges and Rationale
This handout by Lycia Lima, André Portela Souza, and Dalila Figueiredo provides a clear overview of why impact evaluations are important, particularly in understanding the effectiveness of programs and informing better decision-making. It also outlines some of the common challenges that arise during the process, offering useful insights into the practical and methodological difficulties evaluators often face in real-world contexts.
Organizational Challenges of Impact Evaluation
This Goldilocks Toolkit by Innovations for Poverty Action (IPA) discusses various challenges that arise in impact evaluations, as well as the conditions that help overcome the challenges. The guide discusses challenges such as aligning incentives, making tradeoffs, asking the right question, and finding the right timing, among others.

This guide written by Jos Vassen and published by the Institute of Development Policy and Management discusses the scope of impact evaluation as well as some common challenges which plague the process, such as delimitation, attribution versus explanation, etc. Vassen also provides some lessons for randomized experiments and impact evaluation in general.
Challenges in real-world impact evaluations: Some learning on costs and timeliness
This working paper by Jyotsna Puri (Jo) and Francis Rathinam draws on a set of impact evaluations supported under the Open Window funding stream of the International Initiative for Impact Evaluation (3ie). It explores some of the common questions that arise when conducting impact evaluations in real-world contexts, including issues related to costs, the complexity of implementation, and the extent to which evaluations can realistically influence policy.
Case study #
This study by Zid Mancenido examines the limited availability of rigorous impact evaluations in the area of teacher preparation, a concern often raised by teacher education researchers. To explore this issue, the author reviews 166 impact evaluations of teacher preparation practices published in peer-reviewed journals between 2002 and 2019. The study not only highlights common gaps and challenges in existing research but also points to emerging approaches and offers a practical checklist to guide future researchers in designing stronger, more effective impact evaluations.
This study discusses the challenges in carrying out impact evaluations in disaster risk management, especially given the limited use of counterfactual approaches in this area. It brings out the practical as well as methodological challenges involved in evaluating community-based disaster risk reduction efforts in real-world settings. Drawing on a case from the Swiss and Honduran Red Cross in Honduras, the study shows how careful evaluation design can still be applied despite these constraints.
