This article presents the development, results, validation, and implications of the TRansformative Outcomes and PrOcesses Scale (TROPOS), a 30-item, exploratory instrument to assess transformative learning (TL) among participants in educational programs. Core findings include a reliable ([alpha] = 0.884) and internally valid instrument with moderate correlation between transformative processes and outcomes (r = 0.593). This study reflects the importance of critical reflection's association with TL (r = 0.541) but also places potential constraints on its prominence as a central component of TL, raising subtle questions into additional moderating or mediating constructs impacting TL.
