What the data says
Of the 20 pupils who finished Year 11 at Portal House School in 2023, none moved to a sixth form college, 20% to a further education college and none started an apprenticeship.
10% of leavers were not in sustained education, employment or training six months on, compared with 6% nationally.
Almost nobody goes straight into an apprenticeship or a job: none took an apprenticeship and none went into work, against 3% and 3% across England.
Portal House School is a special school: its GCSE figures (Attainment 8 of 13.2, 0% with grade 5 or above in English and maths) are published by DfE for completeness and are not comparable with mainstream schools.
