I work with children with various learning difficulties including dyslexia and they all get 25% extra time, some have a reader and some also have a writer. But they are only entitled to this provision in an exam if they have been assessed by an educational psychologist and in their report state the specific learning difficulty and what what extra support they need in the exam. Then when you complete the application form for the GS exam you have to state that they have a SPLD, which one and what provision they are entitled too. The schools can and probably will require proof of this before allowing it, which would be the Ed Psych report.
Excellent, very useful. DD is having a re-assessment next week and so I will mention to Ed Psych. Thanks
