International research on adult education systems reaches certain limitations when explaining differences between and within countries. Often, research within the multilevel system of adult education examines issues located at the macro-level, meaning policy and legal frameworks, and at the micro-level, dealing with impacts on learners. This article focuses on the meso-level of adult education in two sample countries, referring to providers and their educational offers of publicly financed basic and community education. Guided by the theoretical approaches of educational governance and neo-institutionalism, we identify governance regimes and organizational fields and analyze the impacts of legal and financial regulation on providers and their provision. Based on document review and expert interviews, relations at the national and regional levels are analyzed. We find a decentralized system supporting the regional provision of basic adult education in Spain and a mixture of national and regional regulations leading to regional provision based on learners' needs in England.
