This study employed a qualitative descriptive case study design that investigated the roles of curriculum leadership in South African fee-paying secondary schools in the Gauteng Province. Adopting an interpretive paradigm, the study used Instructional Leadership theory as the theoretical framework. The study’s target population comprised principals and departmental heads in fee-paying secondary schools within the Gauteng Province. Purposive sampling was used to select 12 participants, comprising principals and departmental heads from six secondary schools, to explore the roles of these curriculum leaders through in-depth interviews and document analysis. The data was analysed thematically.
