Schools in Greece have less favourable disciplinary climates in science lessons than in other OECD countries, according to students’ reports in the Programme for International Student Assessment (PISA) 2015, with an index of disciplinary climate of -0.23 (the OECD average index value was 0.00). Student truancy was close to the OECD average: 19.6% of 15-year-olds in Greece reported skipping at least one day of school in the two weeks before the PISA 2015 test, compared to the OECD average of 19.7%. However, students in Greece were more likely to report that their science teachers adapt their instructions more frequently than the OECD average, with an index of adaptive instruction of 0.06 (the OECD average index value was 0.01) (OECD, 2016[1]).
The PISA 2015 index of instructional educational leadership (measuring the frequency with which principals report doing leadership activities specifically related to instruction) was a lot higher than the OECD average (0.24 compared to 0.01) (OECD, 2016[1]). The proportion of lower secondary teachers in 2016 aged 50 or over was 46.8%, which was among the highest in OECD countries (the OECD average was 35.4%). In 2017, teachers in Greece had fewer net teaching hours for general programmes than their peers in other OECD countries. Teachers annually taught 660 hours at primary level and 609 hours at lower secondary level, compared to OECD averages of 784 and 696 hours, respectively.1 Lower secondary teachers earned 115% of the average salary of a full-time, full-year worker with tertiary education in 2016, which was more than the OECD average of 91% (OECD, 2018[2]).
According to school leaders’ reports in PISA 2015, school leaders in Greece are less likely than their OECD peers to conduct self-evaluations of their schools (80.7% of students were in schools whose principal reported this, compared to the OECD average of 93.2%) and also much less likely than average to undergo external evaluations of their schools (20.8% of students were in schools whose principal reported this, compared to the OECD average of 74.6%) (OECD, 2016[1]).
In 2017, 50% of decisions relating to resource management (allocation and use of resources for teaching staff and principals) in Greece were taken at the central level, and 50% were taken across multiple levels, compared to OECD averages of 21% and 14%, respectively. According to school principals’ self-reports in PISA 2015, schools in Greece have some of the lowest levels of autonomy over curriculum compared to other OECD countries: 3.5% of principals reported that the school has primary autonomy over curriculum, compared to an OECD average of 73.4% (OECD, 2016[1]). Annual expenditure per student at primary level in 2015 was USD 5 810, lower than the OECD average of USD 8 631). At secondary level, Greece spent USD 6 786 per student, compared to the OECD average of USD 10 010, while at tertiary level (including spending on research and development) Greece spent USD 4 095 per student, compared to the OECD average of USD 15 656. In 2015, expenditure on primary to tertiary education in Greece as a proportion of gross domestic product (GDP), at 3.8%, was one of the lowest rates in the OECD (OECD average of 5%). The proportion coming from private sources (including household expenditure, expenditure from other private entities and international sources) was lower than the OECD average (8% compared to 16.1%) (OECD, 2018[2]).
