Value added, school quality and student outcomes

In this project, we calculate value-added scores to measure the quality of schools, making comparisons with other quality measures and student outcomes after graduation.

The Swedish education system lacks rigorous measures of school quality. Systematic quality improvement in schools and municipalities rests on the ability to compare schools and track the development of quality. In the project, we calculate value-added scores for schools in Sweden. Value-added scores are an established measure of school quality in the research literature but have hardly come to practical use in the Swedish education system. Value-added scores measure the extent to which schools’ students perform better than what is expected, given their previous results as well as their background characteristics.  

Our goal is to calculate value-added scores for as many Swedish schools as possible. The value-added scores can then be compared with other measures of school quality and student outcomes after graduation. We hope that the value-added approach will win acceptance among schools and come to use in systematic quality improvement.

The project is financed within the research program The Economics of the Service Sector and the applied parts of the project also from the organizations that take part in them including IES and Kunskapsskolan.

International cooperation

Visiting researchers

Collaborating with others is essential for IFN as a research institute. Our researchers co-author articles with colleagues from other institutes, and many also teach at various universities and colleges.

As part of our extensive program of guest researchers, leading international researchers visit the institute. The visitors present and pursue their research as well as interact and cooperate with researchers at IFN.
