This was slightly higher than the OECD average of 1600 hours for primary and 1618 hours for lower secondary education. Net teaching time amounted to 662 hours per school year, which was less than in many other OECD countries (OECD average: 772 hours for primary and 694 hours for lower secondary education) (see Figure 4.1, OECD, 2015a).1 With the implementation of the 2014 Folkeskole reform, it is expected that teachers on average teach 80 hours more during a school year. A school year is usually 40 weeks in Denmark. Countries are ranked in descending order of the number of teaching hours per year in lower secondary education. Lower secondary teachers reported to spend on average 18.9 hours per week teaching, around the TALIS average of 19.3 hours, and 7.9 hours on individual planning or preparation (either at school or out of school), slightly more than the TALIS average of 7.1 hours (see Figure 4.2).
