This study sought to examine the curriculum management enablers and constraints experienced by school principals in KZN rural high schools in King Cetshwayo. A survey research design of the exploratory sub-type was adopted. The findings reveal a lack of parental involvement, increased principals' workload due to multi-faceted responsibilities, difficulty recruiting suitably qualified teachers, lack of teacher development opportunities for teachers, poor infrastructure and facilities, curriculum delivery challenges, curriculum monitoring, and evaluation. The identified deficiencies in curriculum management are linked to the instructional leadership led by the principals.
