Higher education included 416 institutions in 2026, while the number of foreign students reached 307,464. Current school changes include the High School Credit System, the five-grade high-school internal ranking system for cohorts entering from 2025 and revised credit-completion rules from 2026. The Ministry is also expanding AI-related teaching support in schools and funding general AI curricula at selected universities. | The United States operates a decentralized education system in which states and local school districts control most decisions involving curricula, graduation requirements, school administration and teacher licensing. Compulsory attendance rules differ by state, while the common K–12 sequence runs from Kindergarten through Grade 12. Public schools serve about 91% of students in the latest nationally comparable public/private enrollment data, with private schools serving about 9%. English is the main language of instruction, alongside bilingual and dual-language programs in Spanish, Indigenous languages and other community languages. The United States has participated in every PISA cycle since 2000. In PISA 2025, students scored 463 in mathematics, 490 in reading and 502 in science; science was the highest-scoring core domain. Higher education includes research universities, four-year colleges, community colleges and specialized institutions. The 2025 Carnegie classifications designated 187 Research 1 institutions, while international enrollment reached 1,177,766 students in 2024/25. Current federal changes include new AI education initiatives and federal student-loan limits and repayment rules that took effect in 2026. |
