This article advocates for the validity of Realist Evaluation (RE) as a manifestation of Critical Realism in evaluation research despite criticisms suggesting that the former disregards principles from Bhaskarian ontology. Specifically, I argue that critics overstate RE's philosophical actualism in their argument that its inclination towards technocratic knowledge impedes its scrutiny of stratified social systems. Notwithstanding its limitations in fully elucidating causal structural mechanisms in social inquiry, I argue that RE's research rationale can contribute to the stages of explanatory research (...) based on CR by bridging the comprehension of mechanisms linked to micro-interventions with exploring potential structural forces operating across levels of reality. To illustrate this point, I present a case of a policy evaluation study I led that demonstrates how a RE-oriented research design facilitated a transition from investigating specific programme mechanisms within the interventions' context to proposing transcendental questions about the governance of the education system in Colombia.
