One Year Programmes

Students for whom English is a Second Language may apply to join the Bridging programme in either Year 1, 2 or 4 in preparation for joining the mainstream classes the following year.  A general programme is offered mirroring the mainstream programme which enables students to easily join the mainstream the following year.

Students with first language level English applying for Year 4 are generally not eligible for the two year IGCSE programme but may apply to the one year Foundation IB course.
