Growing numbers of private schools are expected to abandon GCSEs after a London school announced it will create its own qualifications, experts warned on Wednesday.The £24,000-a-year Latymer Upper School in Hammersmith will drop all GCSEs apart from English and maths. It said this will stretch pupils further and free up a quarter of its teaching time.Pupils will instead take Latymer’s own qualifications, which have not yet been named, and will end up with a portfolio and transcript of what they have learnt in each subject. Teaching for the new qualification will begin in 2027.
