The American Curriculum is divided into three stages: Elementary School, Middle School and High School. In Elementary School, students aged 4 to 11 enter Kindergarten to Grade 5. Students aged 11 to 14 progress to Middle School which covers Grade 6 to Grade 8. They then move on to High School until the age of 18 to complete Grade 9 to Grade 12. 

The American Curriculum is a standards-based curriculum that is governed by six accreditation authorities including the Middle States Association of Colleges and Schools (MSACS), and the Western Association of Schools and Colleges (WASC). All subject content must abide by the Common Core State Standards or the AERO Common Core Plus Standards. American international schools have the flexibility to design their curriculum based on standards that are relevant to their host country. 

Students need to complete a certain number of credits from Grade 9 to Grade 12 to be granted the American High School Diploma. In addition, students have the opportunity to sit for standardised tests such as the SAT, PSAT and ACT to measure their knowledge in certain subject areas.

Here are the schools in Thailand that offer the American Curriculum:
