Schools in New Zealand 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 -0.15 (the OECD average index value was 0.00). Student truancy was higher than the OECD average: 25% 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%. That being said, students in New Zealand were more likely to report that their science teachers adapt their instructions much more frequently than the OECD average, with an index of adaptive instruction of 0.25, among the highest in OECD countries (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 0.38 (the OECD average was 0.01) (OECD, 2016[1]). In 2016, the proportion of lower secondary teachers in New Zealand aged 50 or over was 40.7%, which was higher than the OECD average of 35.4%. In 2017, teachers in New Zealand had more net teaching hours for general programmes than the OECD average. Teachers annually taught 922 hours at primary level and 840 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, New Zealand’s schools have some of the highest levels of autonomy over curriculum: 95.8% of principals reported that the school has primary autonomy over curriculum, compared to the OECD average of 73.4% (OECD, 2016[1]).
Teachers earned 87% of the average salary of a full-time, full-year worker with tertiary education in 2016, which was below the OECD average of 91%. According to the OECD Teaching and Learning International Survey (TALIS) 2018, 73.7% of teachers in New Zealand said that if they could choose again, they would still become a teacher; this was similar to the OECD average of 75.6%. Furthermore, 33.6% 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 New Zealand are more likely than average to conduct self-evaluations of their schools (99.3% of students were in schools whose principal reported this, compared to the OECD average of 93.2%). They are much more likely than average to undergo external evaluations of their schools (96.7% of students were in schools whose principal reported this, compared to the OECD average of 74.6%). The share of students enrolled in secondary schools, as reported in PISA 2015, whose principal reported that standardised tests are used to make decisions on students’ promotion or retention was 58%, which was more 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: 33% of decisions in New Zealand were taken at the school level, compared to the OECD average of 29%.
Annual expenditure per student at primary level in 2015 was USD 7 849, which was lower than the OECD average of USD 8 631. At secondary level, New Zealand spent USD 10 383 per student compared to the OECD average of USD 10 010, while at tertiary level (including spending on research and development), New Zealand spent USD 15 166 per student, compared to the OECD average of USD 15 656.
In 2015, expenditure on primary to tertiary education in New Zealand as a proportion of gross domestic product (GDP) was 6.3%, which was one of the highest rates in the OECD (the OECD average was 5%). The proportion of expenditure on education (from primary to tertiary) coming from private sources (including household expenditure, expenditure from other private entities and international sources) in 2016 was also higher than the OECD average, at 25.6% of overall spending, compared to an average of 16.1% (OECD, 2018[2]).
