Parents moving children between British-curriculum and American-curriculum international schools often get confused about whether “Year 10” and “Grade 9” are the same level, because the two systems number their year groups differently. This article summarises an easy-to-read year-comparison table, plus the points that most commonly cause confusion, especially around when a child starts IGCSE or A-Level/IB exams.
Based on the year-comparison table commonly used across international education systems. Doris School — UK Year Groups vs US Grades Conversion Chart
UK vs US year comparison table
| UK Year Group | US Grade | Approx. age | Stage |
|---|---|---|---|
| Reception | Junior K | 4-5 | Foundation |
| Year 1 | Kindergarten | 5-6 | Primary |
| Year 2 | Grade 1 | 6-7 | Primary |
| Year 3 | Grade 2 | 7-8 | Primary |
| Year 4 | Grade 3 | 8-9 | Primary |
| Year 5 | Grade 4 | 9-10 | Primary |
| Year 6 | Grade 5 | 10-11 | Primary |
| Year 7 | Grade 6 | 11-12 | Middle School |
| Year 8 | Grade 7 | 12-13 | Middle School |
| Year 9 | Grade 8 | 13-14 | Middle School |
| Year 10 | Grade 9 | 14-15 | High School (IGCSE starts) |
| Year 11 | Grade 10 | 15-16 | High School (IGCSE finishes) |
| Year 12 | Grade 11 | 16-17 | High School (A-Level/IB year 1 starts) |
| Year 13 | Grade 12 | 17-18 | High School (A-Level/IB year 2, finishes) |
The most common points of confusion
- Different cut-off dates — UK uses a September 1 cut-off, while US typically uses an August enrolment date, so children born in the same month can end up in different year/grade levels when switching systems. Always check the exact cut-off policy of the destination school directly, rather than assuming from a general table.
- Year 10 is not the same number as Grade 10 — the most common point of confusion is assuming the same number means the same level, but actually Year 10 (UK) roughly equals Grade 9 (US), one year off from what the numbers suggest.
- The starting point for IGCSE/A-Level doesn’t align neatly with US Grade numbers — a student moving from the US system at Grade 9 lands right at Year 10 (the start of IGCSE), but moving at Grade 10 may need a case-by-case discussion with the school about year placement.
