SDG4 is a key enabler of most other SDGs. Unfortunately, global progress in education has not been fast enough. Only 58% of students worldwide achieved at least the minimum proficiency level in reading at the end of primary schooling in 2019. A large share of countries is moving backwards in learning outcomes at the end of lower secondary school. Improvement in upper secondary completion rate has slowed since 2015. Some regions, including sub-Saharan Africa, are facing teacher shortages, high student-teacher ratios, and inadequate training and lack of professional development opportunities for teachers. Accelerating progress towards SDG 4 should be prioritized as it will have a catalytic impact on achieving the overall 2030 Agenda.
Target 4.1: Completion rates in primary and lower secondary level education continue on an upward curve while the percentage of young people completing upper secondary school increased from 53% in 2015 to 59% in 2023. This increase, however is at a slower pace relative to progress in the preceding eight-year period and such improvements do not always result in positive learning outcomes. Between 2018 and 2022, based on learning outcomes at the end of lower secondary school across 81 OECD and partner countries, mean performance in mathematics fell by a record 15 points while in reading fell 10 points. However, reading and mathematics scores had been declining for these countries prior to 2015, suggesting that COVID-19 explains only part of the decline. A complex set of factors affect the education systems of upper-middle-income and high-income countries.
Target 4.2: Data from 76 mainly low- and middle-income countries from 2015 to 2023 shows that approximately two-thirds of young children are developmentally on track, with no significant gender differences. However, there are wide variations among countries and regions. In 2022, globally, 7 out of 10 children participated in organized learning one year before reaching official primary school age. Despite a 1.5 percentage point decline during the COVID-19 pandemic, participation levels have started to recover and return to pre-pandemic levels.
Target 4.3: In countries with recent data, around one-sixth of individuals aged 15-64 have participated in education and training. Participation is significantly higher among youth aged 15-24 compared to those aged 24-55, with an average participation rate of nearly 50% across most regions. However, less than 3% of older adults aged 25-55 engage in education and training in most regions.
Target 4.5: Socioeconomic disparities are prevalent in education, affecting various indicators. Global and regional parity ratios may hide gender inequalities within countries, disadvantaging either girls or boys. Disparities based on location or household wealth are more pronounced, with rural or less affluent families facing greater challenges. These gaps widen at higher education levels, leading to increased dropout rates and fewer opportunities for those from disadvantaged backgrounds.
Target 4.a: Only half of all primary schools have the basic infrastructures and materials to provide an adequate schooling experience to pupils with disabilities and one in five primary schools globally does not have single-sex sanitation facilities. On average, 44% of primary schools, 56% of lower secondary schools and 69% of upper secondary schools had access to Internet in 2022, almost double the rates in 2021. At the upper secondary level, 91% of schools have access to electricity, 81% have computers for pedagogical use and 69% of schools are connected to the internet.
