Established in 1979,[1] Westisle provides education for 10th to 12th grade students in the western part of the county.

The vice-principals were Lorne MacDougald and Richard Roberts (the school continues to employ two vice principals).

In the beginning, Holland College began to use the school to offer programs such as electronics, cosmetology, office studies, and a "Leadership Institute" to its students in the western part of Prince County.

The courses at Westisle were offered on an extension basis using personnel and resources from the college's Summerside-area campuses.

Students can now attend Holland College in the new West Prince Campus located in Alberton.
