St Johns Park High School, among its fellow high schools, is known for its strict uniform. Michael Juchau, St Johns Park High School's principal for ten years (1997–2007), was adamant in taking pride in the St Johns' uniform and Ms. French, St Johns Park's newest principal did not disappoint, being one of the leaders of the Canberra uniform movement. St Johns Park High School also has a tremendous reputation within the district, which has developed over a number of years for providing outstanding levels of educational services. 
In early 2008 the school announced that a new motto: Safe Respectful Learners would also be used alongside the original motto, Know First Yourself. Banners with the new motto present on them can be seen around school grounds. However many students dislike the new motto and feel that the original motto is more honourable.
