Ulster Assessments is based in County Derry-Londonderry and provides diagnostic SpLD assessments for children and adults across Northern Ireland.

For Derry/Londonderry, local context matters: Derry/Londonderry families often need Northern Ireland-aware dyslexia assessment options because private SpLD capacity outside Belfast can be limited. Families and adults should confirm whether the assessor holds an Assessment Practising Certificate or appropriate psychologist registration, whether the report follows SASC guidance, and whether it will be accepted for school, college, university, workplace, DSA, Access to Work or exam-access purposes.
