Schools in the Slovak Republic 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 -0.13 (the OECD average index value was 0.00). Student truancy in 2015 was also among the highest among OECD countries: 51.1% 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%. Students in the Slovak Republic were also less likely to report that their science teachers adapt their instructions more frequently than the OECD average, with an index of adaptive instruction of -0.24 (the 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 higher than the OECD average, at 0.17 (the average was 0.01) (OECD, 2016[1]). The proportion of lower secondary teachers in 2016 aged 50 or over was 37.7%, compared to the OECD average of 35.4%. In 2017, teachers in the Slovak Republic had similar net teaching hours for general programmes to their OECD peers. Teachers annually taught 794 hours at primary level and 652 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, schools in the Slovak Republic have higher levels of autonomy over curriculum than the OECD average: 84% of principals reported that the school has primary autonomy over curriculum, compared to 73.4% on average (OECD, 2016[1]).
Lower secondary teachers earned 64% of the average salary of a full-time, full-year worker with tertiary education in 2016, compared to the OECD average ratio of 91%. According to the OECD Teaching and Learning International Survey (TALIS) 2018, 76.3% of teachers in the Slovak Republic said that if they could choose again, they would still become a teacher; this was around the OECD average of 75.6%. Furthermore, only 4.5% 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 the Slovak Republic are more likely than average to conduct self-evaluations of their schools (97% of students were in schools whose principal reported this, compared to the OECD average of 93.2%), but less likely than average to undergo external evaluations of their schools (62.4% of students were in schools whose principal reported this, compared to the OECD average of 74.6%) (OECD, 2016[1]). Teacher appraisal levels, as reported in the previous cycle of TALIS 2013, were above average: 93% of all teachers had reported then having received an appraisal in the previous 12 months, compared to the average of 66.1% (OECD, 2014[4]).
The share of students enrolled in secondary schools whose principal reported in PISA 2015 that standardised tests are used to make decisions on students’ promotion or retention was 23%, which was less than the OECD average of 31% (OECD, 2016[1]).
In 2017, school autonomy levels over resource management (allocation and use of resources for teaching staff and principals) were higher than the OECD average: 50% of decisions in the Slovak Republic were taken at the school level, compared to the OECD average of 29%.
The Slovak Republic’s annual expenditure per student at primary level in 2015 was USD 6 877, which was lower than the OECD average of USD 8 631. At secondary level, the Slovak Republic spent USD 6 660 per student, compared to the OECD average of USD 10 010, while at tertiary level (including spending on research and development), the Slovak Republic spent USD 15 874 per student, compared to the OECD average of USD 15 656. In 2015, expenditure on primary to tertiary education in the Slovak Republic as a proportion of gross domestic product (GDP) was 4.4%, which was lower than the OECD average of 5% (OECD, 2018[2]).
