The Swedish school has undergone massive change during the last decades. Going from one of the most centralized school systems to a system dominated by marketization. This change has not come rapidly. Several scholars have argued that if we want to understand this transformation, we must study this over time. In the research project The Open Parliament Laboratory (OPaL) we aim to study this change in policy by looking at parliamentary data. By using Natural Language Processing (NLP) and discourse analysis, we shall study the political debate from the last decades, to better understand how Sweden ended up with one of the most unregulated educational systems in the world.
