Education in law in Norway must be characterised as an open educational field, with lower entry requirements than other prestigious professional fields. Such an open system might be expected to lead to a high degree of equality by social class origin among the graduates. The impact of social origin is assessed at different steps of the educational and occupational career in a unique sample consisting of all Norwegian graduates in law between 1981 and 1996. The results demonstrate that there is a high level of social inequality in academic performance, which is greater at later stages than early in the educational career. Large and increasing income inequality is found also, for graduates with equal levels of academic performance. Various mechanisms that may produce this pattern are discussed, including specific forms of cultural capital, such as knowledge about strategies of self-employment, social and financial capital.
