Reading, writing and literature, mathematics, natural sciences and foreign languages are recognised as core subjects in all European countries. But how much time do students spend on those subjects at school, and how much does this instruction time vary across countries? This report provides information about the recommended minimum instruction time across core subjects in full-time general compulsory education in 37 European countries participating in the Eurydice network. The reference year is 2015/16. The publication offers a comparative overview of the differences between primary and compulsory general secondary education, and identifies the main changes since 2010/11. It also includes national diagrams and maps illustrating the data on minimum instruction time by country and by subject. [For the 2014-2015 report, see ED593463.]
