However, Carmarthenshire’s School Admission Policy is based on the pupil’s home address and not the primary school attended. Gellir cysylltu a'r Adran Dderbyn drwy ffonio 01267 234567 lle y gallwch siarad gyda aelod o staff neu trwy e-bost admissions@carmarthenshire.gov.uk

The admission limit for the School is 260. We also have a number of preferred placements from other schools. 

Parents/Guardians of pupils who are considering entering Ysgol Dyffryn Aman are invited to attend Open Evenings during October. Pupils who will enter the school in September will visit the school towards the end of the Summer Term in Year 6 for Induction days.
