This article, building on the emerging theoretical corpus of “reputation theory” provides an alternative explanation about how successful policies are obtained in contexts of bureaucratic weakness and volatile politics. The argument is that politicians choose to intervene in delivering successful policies based on how contributable such policies are to construct their political reputations. The findings suggest that in both countries, less tenured politicians face higher incentives to build their reputations, so they choose to deliver better policies to accumulate “successful experiences” as vitae for electoral purposes. Tenured politicians, in turn, opt for inaction or strategic delivery, to preserve their already won political reputations. The present article brings evidence from the education sector of Peru and Bolivia, a sector that has been at the core of these countries' priorities for decades. Through a mixed methods approach involving a panel regression and in‐depth interviews, results obtained largely confirm this article's claims.
