Changing schools is particularly disruptive for children in GCSE years, because other schools may not offer the same options as their current school, or they may have a different syllabus or exam board.
Changing schools at this time can affect the subject options available to your child and may negatively affect their final grade as previous coursework marks may be lost.
We would encourage you to discuss this with your child's current school before making an application to change schools.
Please also be aware that limited vacancies are available in these year groups throughout Hounslow.
