St. David Catholic Secondary School, established in 1965, is a Roman Catholic high school instructing students from grades 9 to 12.

Historically, it served as a junior high school, instructing students from grades 7 to 10.

In 1985, St. David received full funding from the Ontario Ministry of Education, due to the school changing its educational focus to students in grades 9 to OAC.

[1] The school has approximately 84 full-time teaching staff.

[citation needed] As with the other secondary schools in the Waterloo Catholic District School Board, St. David requires all students to wear a uniform every day, excepting the occasional dress-down day (known to staff and students as "Civies Day").
