Named after Charles William Jefferys, a Canadian artist whose work has contributed much to education in the areas of Canadian History and Art, the school is home to the Visual Arts Program offered in facilities by a teaching staff, many of whom are practicing artists. The first Head of the Art Department was James Meechan, the stained glass artist, who selected only professional artists for the department staff. Additionally, it is home to the ESTeM Enriched Science, Technology and Mathematics Program - a project based, hands on, exploratory approach to the Sciences, Mathematics, and Computer Technology. Students at C. W. Jefferys consistently rank among the top winners in mathematics and science competitions, and each year, many of them are recipients of numerous bursaries and entrance scholarships to some of the province's top colleges and universities. The post-secondary acceptance rate is 75%. This helped by student success initiatives supporting "at risk" students through the Learning to 18 pilot project, "Stay Connected" and the credit recovery program offered at the school.
