1. Passports and visas
Verify passport validity for every student and staff member against destination-country requirements at the 6-month mark, not the final week. Identify non-UK/Irish passport holders early — Schengen visa processing can take 4–8 weeks, longer at peak periods. Some countries require additional documentation for under-18s travelling without parents (parental authorisation letters in Spanish or Portuguese, notarised in some cases).
