[year missing][citation needed] The main historical source is local historian F. A. Bailey's 40 page pamphlet published to celebrate the 400th anniversary of the school in 1944 and reissued in 1971 under the title PGS 1544 - 1971 with postscripts by G. Dixon and the then headmaster, J. C. S. Weekes.

The next move was to the spacious site on St. Helens Road, accommodated in newly built wooden buildings which were originally intended to be temporary, but were expanded and augmented in the 1960s by a brick-built assembly hall ("Spencer Briggs Hall"), classrooms and purpose-built metalwork and woodwork workshops, and remained in use until 1978 when they fell victim to an arson attack by a disturbed former pupil.

Headteachers include C. W. H. Richardson, who ensured the school's survival during difficult times in the 1920s and 1930s, and R. Spencer Briggs from 1937 to 1963.

There was also extracurricular activity: debating, amateur dramatics, choral and instrumental music, and school societies.

The extensive playing fields of the boys' school in St Helens Road were sold off and are now covered by a housing development.
