School self-evaluation is the primary method of delivering school evaluation in Norway. There is a statutory requirement for schools to undertake self-evaluation, using the data provided to them through the School Portal. The Directorate for Education and Training has developed methodological analysis tools for schools to help them review their practice. The school owners are required to implement a quality framework and ensure that their schools have self-evaluation processes in place. While practices vary, school owners tend to operate an approach whereby they monitor results, require schools to submit annual plans and occasionally visit schools to conduct a “quality dialogue” and check compliance of school policies with regulations. There are no national systematic inspections or external reviews of individual schools. While there has been increasing focus on quality work at the school level, the extent, rigour and quality of evaluation across schools in Norway is variable. Many schools and school owners struggle to use data effectively for improvement and there was insufficient focus on observing and evaluating actual teaching and learning practice. There was a lack of advice on methodologies or quality standards that school leaders could use to develop a systematic view of the quality of teaching and learning across the school.
