This study explores ICT integration from a school improvement approach. More particularly, it examines the local school policy with respect to ICT integration from both the principal's perspective and perceptions of teachers. Furthermore, it measures the relationship between ICT school policies and the effective use of ICT in the classroom. A representative sample of 55 principals was interviewed. In view of research question 2, the data of the principals were linked to the data from a survey of 574 teachers within the same elementary schools. What emerged in our multilevel model was that school policies eg, an ICT plan, ICT related support and ICT training have a significant effect on class use of ICT. Nevertheless, in this study, ICT school policies are often an underutilised means. The results suggest that principals have to develop a more collaborative approach when defining this policy. The study underpins the importance of a shared and school-wide vision about ICT integration that reflects the opinions and beliefs of the principal, the ICT coordinator, and the teachers.
