Although boarders are encouraged to be self-reliant and explore Central London, they require that, for their own protection, they sign in and out of the boarding house using the Houseparents' and the College's mobile numbers. All students are expected to attend all meetings and school events where they might be needed, and they must return by the appropriate curfew. Students under the age of sixteen who are required to be in school must check out in groups and return to the house in the same groups. To ensure that everyone knows what to do in the unlikely case of an emergency, they have full fire and lockdown drill procedures in place in addition to round-the-clock security on site.
