Immanuel College pupils visited a strictly Orthodox special needs school in Stamford Hill they have raised thousands of pounds for.
Thirty students from the Bushey school's Shevet Achim committee were invited to Side by Side - one of the three charities supported. The visitors were given a tour of the school and helped the children with some of their activities.
Taliya Ambalo, 14 - the pupil who introduced the committee to Side by Side - said the group had been "enriched by the experience". A Side by Side representative said staff were impressed that pupils "wish to be involved in enhancing the lives of children with special educational needs".
