Additionally, it is one of six high schools that provides a location for The Work Room, an Anglophone South career consultation and resource centre.

The foundation work for the school was scheduled to start before the end of November, extending throughout the winter months, with the remainder of its first phase of construction to be contracted after its completion.

Despite being built in Quispamsis, the school was designated to serve students from the nearby communities of Rothesay, Kingston, and Hampton as well.

[7] In April 1974, this first phase of KVHS had an estimated completion date set for August 1975, accommodating a capacity of approximately 1,000 to 1,200 students.

[8] In March 1973, foundation work for the new school was still underway, and it was expected by later that month that specifications for the general construction contract would be ready for tender call.

[9] In late 1973, following a several-week long postponement,[10] the Goodyear Paving Company was granted a contract worth $4,861,911 (equivalent to $26,276,588 in 2021) for the first phase of the school's construction.

[16] On March 4, 2022, Kennebecasis Valley High School announced its decision to replace their longstanding mascot “Ken the Crusader” with "Knickie the Blue Knight," marking a transition following nearly 50 years.

[33][34] Kennebecasis Valley High School has found success in the annual Reach for the Top tournaments, where they often win the provincial championships.

Its drama club was created and organized in October 1975, with its first production, Thornton Wilder's Our Town,[63] which would only be played to staff and students,[64] scheduled for early November.

Additionally, there were plans underway for the school's first musical production, The King and I,[65] which, following an assembly announcement in January 1976, attracted nearly 200 student volunteers,[64] to be presented "some time in April or May".
