Around 1950 was Norway behind the European average in educational attainments, with larger impacts of class background and gender. This changed during the next fifty years. Especially as a consequence of the expansion of compulsory education around 1960, which especially diminished the attainment impacts of class background. But the new policies of the 1990s, that expanded higher education, strenghtened its research element, and revised upper secondary curricula to support these developments, produced a fallback in these developments. The educational mobilisation of he women proceeded largely independently of policies.
