CNS is a four–semester program, with required courses available year–round. That means you can choose to complete your studies in four consecutive semesters, starting in the fall, winter or spring. Or you could take a break between semesters.

Courses in this program are hands–on, helping you get the most out of your studies. Some of the courses you’ll learn by experience include: computer hardware, applied Internet technology, system diagnostics, local area network installation and maintenance, data communication techniques and network administrative tasks.

Once you reach your third semester, you’ll have the opportunity to apply for transfer to the six– semester CTY co–op program.
