The Use of Evaluability Assessments in Improving Future Evaluations: A Scoping Review of 10 Years of Literature (2008–2018)

Abstract

Since the beginning of the 21st century, evaluability assessments have experienced a resurgence of interest. However, little is known about how evaluability assessments have been used to improve future evaluations. In this article, we identify characteristics, challenges, and opportunities of evaluability assessments based on a scoping review of case studies published since 2008 (n = 59). We find that evaluability assessments are increasingly used for program development and evaluation planning. Several challenges are identified: politics of evaluability; ambiguity between evaluability and evaluation, and limited considerations of gender equity and human rights. To ensure relevance, evaluability approaches must evolve in alignment with the fast-changing environment. Recommended efforts to revitalize evaluability assessment practice include the following: engaging stakeholders; clarifying what evaluability assessments entail; assessing program understandings, plausibility, and practicality; and considering cross-cutting themes. This review provides an evidence base of practical applications of evaluability assessments to support future evaluability studies and, by extension, future evaluations.
