In terms of learning environments, student truancy in Belgium was among the lowest in the OECD: only 7.1% 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%. At the same time, schools in Belgium 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 -0.16 (the OECD average index value was 0.00. Students in Belgium were also less likely to report that their science teachers adapt their instruction more frequently than the OECD average, with an index of adaptive instruction of -0.38 (the average index value was 0.01) (OECD, 2016[1]).
The PISA 2015 index of professional development leadership in Belgium (measuring the frequency with which principals report doing leadership activities specifically related to staff professional development) was 0.12, compared to an OECD average of -0.01. However, the index of instructional educational leadership (measuring the frequency with which principals report doing leadership activities specifically related to instruction) was lower than the OECD average at -0.31 (the OECD average was 0.01) (OECD, 2016[1]). In 2016, the proportion of lower secondary teachers aged 50 or over was 28.2%, which was below the OECD average of 35.4% (OECD, 2018[2]). However, recent information from the Flemish and the French Communities of Belgium points to a growing teacher shortage from 2018 onwards that will have to address ways of mitigating the replacement of retiring teachers and attracting new teachers to the profession (National data reported to the OECD). According to the OECD Teaching and Learning International Survey (TALIS) 2018, 78.8% of teachers in Belgium said that if they could choose again, they would still become a teacher; this was higher than the OECD average of 75.6%. (OECD, 2019[3]).
According to school leaders’ reports in PISA 2015, school leaders in Belgium are less likely than average to conduct self-evaluations of their schools (84.7% of students were in schools whose principal reported this, compared to the OECD average of 93.2%), but more likely than average to undergo external evaluations of their school (85.7% of students were in schools whose principal reported this, compared to the OECD average of 74.6%). According to school principals’ self-reports in PISA 2015, schools’ levels of autonomy over curriculum in Belgium are close to the OECD average: 75.4% of principals reported that the school had primary autonomy over curriculum, compared to the average of 73.4% (OECD, 2016[1]).
Belgium has three autonomous education systems (for the Flemish Community, the French Community and the German-speaking Community). The role of the federal government is limited, while the distribution of decision making also differs within each Community. In 2017, school autonomy levels over resource management (allocation and use of resources for teaching staff and principals) were higher within the Flemish Community of Belgium than the OECD average: 50% of decisions were taken at the school level, compared to the OECD average of 29%. In contrast, within the French Community, 25% of decisions were taken at the school level and 25% across multiple levels (OECD, 2018[2]).
Annual expenditure per student at primary level in Belgium in 2015 was USD 10 211, which was above the OECD average of USD 8 631. At secondary level, Belgium spent USD 13 070 per student, compared to the OECD average of USD 10 010, while at tertiary level (including spending on research and development), Belgium spent USD 17 320 per student, compared to the OECD average of USD 15 656. In 2015, expenditure on primary to tertiary education in Belgium as a proportion of gross domestic product (GDP) was 5.7%, which was above the 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 (6.8% compared to an average of 16.1%). However, the relative proportion of public expenditure on education from primary to tertiary was 93.2%, compared to the OECD average of 82.7%. Between 2010 and 2015, the relative proportion of public expenditure on primary to tertiary education decreased by 0.8 percentage points, compared to an average decrease across the OECD of 1.3 percentage points (OECD, 2018[2]).
