Schools in Mexico have slightly more 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 0.04 (the average index value was 0.00). However, student truancy was higher than the OECD average: 25.8% 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 Mexico 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 0.32, 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 lower than the OECD average at -0.23 (the OECD average was 0.01) (OECD, 2016[1]). In 2017, teachers in Mexico had more net teaching hours for general programmes than the OECD average: teachers annually taught 800 hours at primary level and 1 047 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 Mexico have lower levels of autonomy over curriculum than the OECD average: 33.6% of principals reported that the school has primary autonomy over curriculum, compared to the average of 73.4% (OECD, 2016[1]).
According to the OECD Teaching and Learning International Survey (TALIS) 2018, 92.2% of teachers in Mexico said that if they could choose again, they would still become a teacher; this was higher than the OECD average of 75.6% and the highest rate across OECD countries. Furthermore, 41.7% 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 Mexico are less likely than average to conduct self-evaluations of their schools (86.1% of students were in schools whose principal reported this, compared to 93.2% on average) and slightly less likely to undergo external evaluations (73.9% of students were in schools whose principal reported this, compared to 74.6% on average) (OECD, 2016[1]). Teacher appraisal levels, as reported in the earlier cycle of TALIS 2013, were higher than average: 84.5% of all teachers had reported then having received an appraisal in the previous 12 months, compared to 66.1% on average (OECD, 2014[4]).
In PISA 2015, the share of students enrolled in secondary schools whose principal reported that standardised tests are used to make decisions on students’ promotion or retention was 48%, compared to 31% on average (OECD, 2016[1]).
In 2017, all decisions on resource management (allocation and use of resources for teaching staff and principals) in Mexico were taken at the central and state levels, compared to only 30% for the OECD average. Annual expenditure per student at primary level in 2015 was USD 2 874, which was among the lowest in the OECD (the average was USD 8 631). At secondary level, Mexico spent USD 3 129 per student, compared to the OECD average of USD 10 010, while at tertiary level (including spending on research and development), Mexico spent USD 8 170 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) in Mexico was 5.3%, compared to the OECD average of 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 2015 was relatively high at 20.2% of overall spending, compared to the OECD average of 16.1%. Between 2005 and 2015, the relative proportion of public expenditure on primary to tertiary education increased by 0.5 percentage points, compared to an average fall across OECD countries of 1.3 percentage points. During the same period, private expenditure decreased by 1.8 percentage points, compared to an OECD average increase of 10.6 percentage points (OECD, 2018[2]).
