Over the last decade, criminal justice scholars have increasingly endorsed "evidence-based practices"; however, some criminologists have voiced concerns over the varied methodological rigor used by evaluation researchers, differing definitions of evidence, and lack of critical exploration as to why programs may be (in)effective. This article argues that evaluability assessments (EAs) can answer these concerns. Through a case study of an EA used on a prison-based fatherhood program, this article demonstrates how EA's approach leads to a more precise understanding of outcome operationalization, and allows for the democratization of research, which is particularly important in a carceral setting.
