Notes:
- Depending on region, Nursery School may be in the same school as the primary grades
- Reception Year is a bit more structured than Nursery School for 4-year-olds
- In some regions, middle school comes between primary and secondary school. Grades vary, but may go from something like Year 6 to year 8.
- 6th Form is the old term for Years 12 and 13. Depending on region, students may have to go to a separate 6th Form college or they may be able to stay at the same secondary school.
- Magic folk don't have primary schools. They are either home-schooled or sent to muggle primary schools (see JKR's website)
- There is no magical university. After Hogwarts, students find jobs or become apprentices.
en - Depending on region, Junior Kindergarten may or may not be mandatory. Some regions don't have JK. In that case, Senior Kindergarten is just called Kindergarten.
- In the United States, it is common to have middle school from grades 6-8. However, some districts/states/whatever run on the older system of junior high from grades 7-9. The grades of these institutions may vary slightly by region.
- In Canada, some larger cities have middle school/junior high in grades 7-8.
