Since September 1999 one new school, in Buckinghamshire, has been designated as a grammar school. The school opened in September 1999 and was established in substitution for a closing grammar school. Information held on proposals to establish new schools made prior to September 1999 is not reliable and has therefore not been included.
Section 104 of the School Standards and Framework Act 1998 provides that no new additional grammar schools may be established. There are 164 designated grammar schools, and this number has remained constant since 1999. Section 104 provides that a new school may be designated as a grammar school only if it is established in substitution for a closing grammar school or schools.
