Professional credibility cycles in education: Constructing trust and expertise in a regulated state school system.

This article examines how professional credibility is constructed, applied, and recognized among education professionals and managers within a highly regulated bureaucratic setting, specifically a rural elementary state school in Brazil. Using the "credit cycle" framework from science and technology studies—which conceptualizes credibility as a cyclical process of investment, accumulation, and conversion—the study employs ethnographic methods to analyze how educators navigate institutional demands, career trajectories, and group dynamics through activities such as project-based education and report card production. Findings reveal that professional credibility in this context is relational, transactional, dynamic, and cyclical, shaped by the interplay between bureaucratic norms, community expectations, and individual career strategies. The research extends the credit cycle concept beyond scientific laboratories to primary education, highlighting how education professionals convert bureaucratic requirements into professional capital to stabilize or advance their roles, and calls for further application of this framework across diverse professional domains.
