Curriculum management serves as a key factor in improving the quality of education in the Package C Program, which provides alternative learning opportunities for individuals outside the formal education system. This study aims to analyze the practices of curriculum planning, implementation, and evaluation to enhance the quality of non-formal education. Using a descriptive qualitative approach with a multi-site design, this research examines curriculum management in improving educational quality within the Package C Equivalency Education Program at PKBM Seroja, Riau.

Data were collected through in-depth interviews, participatory observations, and document analysis of official school records. Data analysis followed the model of Miles et al. (2014), including data reduction, data display, and conclusion drawing. The findings reveal that curriculum management at PKBM Seroja has been carried out adaptively through participatory planning, flexible organization, andragogical learning approaches, and project-based evaluation. However, several challenges persist, such as limited tutor competence, inadequate facilities, and insufficient operational funding.
