The 1950s saw the creation of a new sports level and the building of the Tillotson Pavilion, and a grant from the Industrial Society funded the construction of a new Boys' Division chemistry block which opened in 1958.

Other additions to the school's facilities include the sports complex and swimming pool in 1986; the Arts & Conference Centre, opened by Diana, Princess of Wales in 1993; and Patterdale Hall, an outdoor pursuits centre at the southern end of Ullswater in the Lake District.

[7][8] [9] After ten years planning, building work began on the £7million co-educational Riley Sixth Form Centre in the Summer of 2012[10] and the facility was ready for use in the Autumn Term 2013.

It stands where Leverhulme envisaged a chapel and has been described as a secular and modern interpretation of the original plan uniting the Girls' and Boys' Divisions.

[13] The Boys' Division has a strong sporting heritage, with in-school trophies for football, cricket and gymnastics dating back 100 years.

[16] In Year 11, pupils are encouraged to take part in National Citizen Service, which feeds into the Sixth Form Community Action scheme.

Pupils gain experience of the world of business and commerce through the 'Business Awareness' course held at Patterdale Hall.

The team at Patterdale Hall, alongside outdoor education staff based in Bolton, assists girls and boys in achieving the expedition part of their Duke of Edinburgh's Award.

Named "Tenacity of Bolton", the ketch allowed Year 8 and 9 pupils the chance for sailing voyages in the Irish Sea.

In order for the school to differentiate itself, additional appropriate symbols were added: The Girls' Division was given permission to display the same arms on a lozenge (i.e. diamond) surmounted by a true-lovers' knot.

This is unusual in heraldry; although unmarried ladies' parental coats of arms would be displayed in this manner, female institutions such as convents normally utilise a shield.

The Old Girls' and Old Boys' Association organises reunions and events, keeps former pupils informed of current events at the school and of the successes of their peers, and invites Old Boys and Old Girls back to the school to share their expertise and life experiences with current pupils.
