Paragraph 1 of Schedule 11 provides that section 85(1) (admissions), so far as relating to sex, does not apply in relation to a single–sex school. There is no general exception to the provisions of section 85(2).
Schedule 11, however, expressly moderates the provisions of section 85(2)(a) to (d) in relation to those single-sex schools which admit a comparatively small number of pupils of the opposite sex, whose admission is confined to particular courses or classes.
Paragraph 1(4) provides that, in the case of such a school, section 85(2)(a) to (d), so far as relating to sex, does not prohibit confining pupils of the same sex to particular courses or classes.
