How do Year levels and Grade levels compare?
What is a Key Stage?
Year level and approximate Grade level equivalence, Key Stages, approximate student ages and other school standards can be compared as in the following table:
Comparison with other school systems: Key Stage/ Year Level/ Grade Equivalence| UK Key Stage | Age | Expected Level | UK | US | Canada | Caribbean |
| Foundation | 03-04 | Nursery | Pre-School | Pre-School | Pre-School | |
| Foundation | 04-05 | Reception KG | Pre-KG | Junior KG | KG | |
| One | 05-06 | 1 | KG | Senior KG | Infants | |
| One | 06-07 | 2 | 2 | 1st Grade | Grade 1 | Standard 1 |
| Two | 07-08 | 3 | 2nd Grade | Grade 2 | Standard 2 | |
| Two | 08-09 | 4 | 3rd Grade | Grade 3 | Standard 3 | |
| Two | 09-10 | 5 | 4th Grade | Grade 4 | Standard 4 | |
| Two | 10-11 | 4 | 6 | 5th Grade | Grade 5 | Standard 5 |
| Three | 11-12 | 7 | 6th Grade | Grade 6 | Form 1 | |
| Three | 12-13 | 8 | 7th Grade | Grade 7 | Form 2 | |
| Three | 13-14 | 5-6 | 9 | 8th Grade | Grade 8 | Form 3 |
| Four | 14-15 | 10 | 9th Grade | Grade 9 | Form 4 | |
| Four | 15-16 | Ext. I/GCSE Exams |
11 | 10th Grade | Grade 10 | Form 5 |
| Five (Sixth Form) | 16-17 | Ext. AS Exams | 12 | 11th Grade | Grade 11 | Lower VI |
| Five (Sixth Form) | 17-18 | Ext. A2 Exams | 13 | 12th Grade | Grade 12 | Upper VI |
Please note that the purpose of the table above is to give guidance on students' expected ages in each Year level in CPHS. It also attempts to explain the associated Key Stages and National Curriculum expected levels for children in each Year group.
Note that the qualifying age for the Year/Grade levels in the above table varies from country to country. In CPHS students' ages are calculated as on 1st Sep in that academic year. In other jurisdictions age is calculated as from other dates such as 1st October or 1st January. The "age" shown in the column above is therefore an approximation and should not be used to define equivalence between one country and another.
Children applying for places in Years 1 to 10 in CPHS are evaluated prior to an offer being made.
