St Oswald’s is a small school of six classes: Nursery, Elvet, Dunelm, Neville, Kingsgate and Bailey. There are 20 children per year group (cohort) from Reception to Year 6. Due to the size of our school building, most classes are mixed age with the exception of Year 6, who are taught separately. The configuration of our classes means that children in Year 1 and Year 4 are split in two equal groups across two classes. Children in these year groups are placed into the class which provides the best balance for them academically and socially. Children still mix as a year group at all other times, as well as for some lessons. Our class structure is outlined below
| Year Group | |
| Nursery | Nursery |
| Elvet | Reception and Year 1 |
| Dunelm | Year 1 and Year 2 |
| Neville | Year 3 and Year 4 |
| Kingsgate | Year 4 and Year 5 |
| Bailey | Year 6 |
