This encompasses the following actions: define and communicate the role of instructional leaders, provide school leaders with training, support and capacity enhancement, develop networks for school leaders to share and work together on improving instruction. A pilot project was developed in preparation for school-based programmes on class management and professional development for teachers in numeracy and literacy. It resulted in recommendations for full-scale implementation of the programme: strengthen the competence of school leaders in pedagogical and collaborative leadership, establish and communicate clear goals for the project to all participants, strengthen professional working environments for teachers within schools (particularly the capacity of schools to reflect on their organisational and pedagogical practices and implement collective learning processes), and increase the quality of teaching methods and practices, including the learning and social environments for pupils.
