This study investigated the challenges facing head teachers in providing leadership support for the implementation of the Competence-Based Curriculum (CBC) in public primary schools in Muleba District, Tanzania. The study was guided by one specific objective: to identify the challenges faced by head teachers in providing leadership support for CBC implementation. Grounded in Hallinger and Murphy's (1985) Instructional Leadership Theory, the study adopted a pragmatic paradigm with a convergent parallel mixed-methods design. The target population comprised 2,166 individuals from 237 public primary schools. Data were collected using structured questionnaires from 112 respondents (100 classroom teachers and 12 heads of schools), semi-structured interviews with head teachers and one School Quality Assurance Officer, and document review. Quantitative data were analysed using descriptive statistics through SPSS Version 22, while qualitative data were analysed thematically following Braun and Clarke's (2006) framework. The findings revealed seven interconnected challenges: inadequate CBC training for head teachers themselves (84.8%), inadequate funding preventing leadership support (81.3%), heavy administrative workloads (76.8%), unclear government support (76.8%), financial constraints generally (67.9%), overcrowded classrooms (64.3%), and teacher resistance to CBC changes (52.7%). The study concluded that head teachers' effectiveness in leading CBC implementation is systematically undermined by systemic factors beyond their control. The study recommends mandatory CBC training for head teachers, reduction of administrative workloads, increased capitation grants with CBC-specific allocations, clear national implementation guidelines, and investment in school infrastructure.
