Education systems use various tools and indicators based on demographic, administrative, and contextual data to monitor and ensure quality education. According to OECD findings, countries rely on national standardized assessments, international benchmarking, and stakeholder and longitudinal surveys. Most have established comprehensive national indicator frameworks and publish annual statistics. School principals identified key quality assurance measures, including systematic recording of attendance, professional development, tracking test results and graduation rates, and conducting internal evaluations.
The OECD links greater school autonomy with improved mathematics performance, noting that quality-assurance mechanisms such as teacher mentoring, classroom observations, and systematic recording of student outcomes are influential.
For equity, the OECD emphasizes that education policies should prioritize responsiveness and flexibility in study pathways, school choice, curriculum design, and teaching strategies. Flexibility allows schools to adapt curricula, innovate, and address local challenges. Balancing vocational and academic options to align with students' and labour market needs is encouraged, while maintaining consistent quality.
Socio-economic disparities in student performance persist, with advantaged students scoring on average 93 points higher in mathematics than disadvantaged peers across OECD countries. This gap is over 93 points in 22 countries and 50 points or less in 13, highlighting continuing challenges in equity.
Higher education generally improves job prospects and earnings, though benefits depend on factors like age, gender, field of study, and labour market participation. Globally, gender wage gaps persist regardless of education level or programme type.
