I think they are saying he needs extra help at school, perhaps via schemes like School Action Plus. Lots of kids at our nearby school are on this - it can mean extra half hour lessons sometimes at lunch break or before school, but they are quite fun and are about stimulating learning enjoyment as much as anything else. The one at our school is called Jump Ahead, and is for kids who might be a little behind in reading, or have some kind of problems with writing, or movements in PE. It could cover mild dyslexia or mild dyspraxia. Don't worry, although I know it must be a shock, but ring the school and ask them exactly what the needs are - there should be a SENCO (Special Educational Needs co-ordinator) who should really tell you what's going on. Good luck, I'm sure it is something very minor like the above.
