The State of Education is a systematic review of developments in Dutch education. It serves as a basis for evaluation of education practice and the education system, and provides input for education policy. The State of Education is published since 1817 by the Inspectorate of Education. The report is based on research, which is presented in readable report with infographics. The production process is characterised by cocreations within multidisciplinary teams (including inspectors and academics). The impact of the Dutch State of Education is high. It is an important background report for education practitioners, policy makers, politicians, media and academics. This is not only a consequence of the high quality, the relevance, the neutral/independent character and the readability of the report, but also of the dissemination activities and dialogue after the publication. One of the major topics in the State of Education in the last years has been inequality in education. The report showed that inequality increased in Dutch education. In the last decade, the success of students became more dependent on their socioeconomic status. In the years 2016–2020, the State of Education discusses different underlying mechanisms that caused this increase in inequality, like segregation, teacher bias, support, school differences and unequally distributed teacher shortages.
