My son currently studies at an IB school which they follow IB K-12 curriculum. I'm planning to move him to a British school.
However, there's one big concern regarding his age. He's going to grade 5 next school year which means he will have 8 more years, inclusive, until graduation from high school (until grade 12).
As his birthdate falls on November, in a British school he'll be assigned for Year 5 for the next school year which means he'll have 9 more years until he graduates high school (which is Year 13 in the British curriculum).
Does that mean my son will be one year behind if I move him to a British school?
Your response is highly appreciated!
