The Council of the European Union has set the goal of reducing low achievement in reading, mathematics and science among 15-year-olds to less than 15 % by 2020. How are European countries going to achieve this? One of the key elements in the learning process is the instruction time available to students. In fact, not only the quality of instruction but also the time spent for learning can have a positive effect on students' learning process. This instruction time report analyses the recommended minimum instruction time in full-time compulsory general education in 43 European education systems for the year 2018/19. Special attention is paid to reading, writing and literature, mathematics, natural sciences and social studies. The report outlines how reading, writing and literature are the subject areas that take up the largest share of instruction time, especially in primary education. Mathematics represents the second largest share of instruction time. In addition to the comparative analysis, the report also includes national diagrams that illustrate data by country and subject, collected jointly by the Eurydice and the Organisation for Economic Co-operation and Development Network for the Collection and Adjudication of System-Level Descriptive Information on Educational Structures, Policies and Practices (OECD NESLI) networks.
