In addition, initial preparation could prepare school principals better for their role and there are no further development opportunities for school principals. Also, the administrative responsibilities of principals and the lack of a stable teaching body may make it difficult for principals to develop learning communities in their schools. Finally, school principals could require further support from teacher leaders and the high degree of centralisation makes it difficult for principals to build a leadership team. In addition, it is important to keep the curriculum of general programmes relevant for the continuation of studies at a higher level while increasing the flexibility of its delivery to take into account the increasing diversity of student achievement as students make progress within the education system.
