General Overview (Narrative)
| Category | Japan | Estonia |
|---|---|---|
| Overview | The Japanese Education System combines national curriculum standards with local administration and a 6-3-3-4 structure. The first nine years—elementary and junior high school—are compulsory and predominantly public, while senior high school participation is widespread. Governed nationally by MEXT, the system also includes private schools, colleges of technology, junior colleges, and a large private university sector. Tokkatsu activities such as student-led cleaning and lunch service form part of school life alongside academic study. Japan participated in PISA in 2000, 2003, 2006, 2009, 2012, 2015, 2018, 2022, and 2025. In PISA 2025, Japan scored 525 in mathematics, 503 in reading, and 538 in science, with all three averages above the OECD mean. Recent changes include the GIGA School Program, the Common Test for University Admissions, elementary class-size reductions, digital learning materials, and the addition of Informatics to the university entrance testing structure. National universities remain an important part of Japan's research and higher education system. | Estonia operates a public-led education system in which national authorities set standards while municipalities manage much of local school provision. Children normally begin basic school at age 7. Basic education lasts nine years, followed by general upper-secondary or vocational pathways, and the learning obligation now continues to age 18 unless secondary or vocational education is completed earlier. Preschool participation is high among children aged three to five. The statutory school year begins on 1 September, with general education providing at least 175 study days. Estonia is also moving basic education toward Estonian as the common language of instruction, with the transition being introduced grade by grade. In PISA 2025, Estonia scored 508 in mathematics, 499 in reading and 527 in science, making science its highest-scoring core domain. Higher education was provided by 18 institutions in 2025, including universities and professional higher education institutions. Foreign degree students numbered 3,879 in 2025/26, representing 8.2% of the student body. Current school changes include the extended learning obligation, the continuing language transition and the teacher career model introduced in 2026. |
