The massification of secondary schooling constitutes the key educational project of the first post-war period. However, the resulting educational structures differed in terms of streaming and standardization. Despite their historical opposition to such expansion, center-right parties contributed to shaping these reforms. They generally opposed standardization because their distributive strategy rested on support from elites and middle classes. However, their stance on streaming varied. Centre-right parties supported streaming when they were linked to teachers and private providers who opposed comprehensive reforms, but supported de-streaming where such groups aligned with the left. This article shows how center-right parties in Bavaria, France, and Italy, with common partisan distributive aims, introduced varied public service reforms following from their links to different vested producers. It argues that theorizing such reforms requires considering both distributive and productive environments.
