Schools in Turkey have less favourable disciplinary climates in science lessons compared to other OECD countries, according to students’ reports in the Programme for International Student Assessment (PISA) 2015, with an index of disciplinary climate of -0.12 (the OECD average index value was 0.00). Student truancy was among the highest among OECD countries: 47% of 15-year-olds 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 Turkey 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 0.12 (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 among the highest in the OECD at 0.54 (the OECD average was 0.01) (OECD, 2016[1]). The proportion of lower secondary teachers in Turkey in 2016 aged 50 or over was 5.4%, which was among the lowest in the OECD (the average was 35.4%). In 2017, teachers in Turkey had fewer net teaching hours for general programmes than the OECD average. Teachers annually taught 720 hours at primary level and 504 hours at lower secondary level, compared to OECD averages of 784 and 696 hours, respectively (OECD, 2018[2]). According to school principals’ self-reports in PISA 2015, Turkish schools have lower levels of autonomy over curriculum, compared to the OECD average: 21.8% of principals in Turkey reported that the school has primary autonomy over curriculum, compared to the OECD average of 73.4% (OECD, 2016[1]).
Lower secondary teachers earned 80% of the average salary of a full-time, full-year worker with tertiary education in 2016; this was less than the OECD average ratio of 91% (OECD, 2018[2]). According to the OECD Teaching and Learning International Survey (TALIS) 2018, 74.5% of teachers in Turkey said that if they could choose again, they would still become a teacher; this was similar to the OECD average of 75.6%. Furthermore, 26% of teachers felt that the teaching profession was valued in society, compared to an OECD average of 25.8% in 2018 (OECD, 2019[3]).
According to school leaders’ reports in PISA 2015, school leaders in Turkey are about as likely as the OECD average to conduct self-evaluations of their schools (93.5% of students were in schools whose principal reported this, compared to the OECD average of 93.2%) and more likely than average to undergo external evaluations of their schools (78.8% of students were in schools whose principal reported this, compared to the OECD average of 74.6%). In Turkey, the share of students enrolled in secondary schools whose principal reported in PISA 2015 that standardised tests were used to make decisions on students’ promotion or retention was 32%, which was close to the OECD average of 31% (OECD, 2016[1]).
In 2017, provincial/regional autonomy levels over resource management (allocation and use of resources for teaching staff and principals) were higher in Turkey than the OECD average: 25% of decisions in Turkey were taken at this level, compared to the OECD average of 7%.
Turkey’s annual expenditure per student at primary level in 2015 was USD 4 134, which was among the lowest among OECD countries (the average was USD 8 631). At secondary level, Turkey spent USD 3 511 per student, compared to the OECD average of USD 10 010, while at tertiary level (including spending on research and development), Turkey spent USD 8 901 per student, compared to the OECD average of USD 15 656. In 2015, expenditure on primary to tertiary education as a proportion of gross domestic product (GDP) was 4.8% in Turkey, which was lower than the OECD average of 5%. The proportion coming from private sources (including household expenditure, expenditure from other private entities and international sources) was higher than the OECD average (21% compared to 16.1%) (OECD, 2018[2]).
