Yes, and no; you can take all of your courses online at one of the colleges listed below, or only a selected few, such as they are noted at the other college. Most students looking for online classes are doing so for time constraints and flexibility of schedule. For example, the class "Industrial Fire Protection" at a "brick and mortar" college may only be offered at 2pm on M-W-F. How can you participate in this course if you are working full time? Compare this to a online course, where a professor gives you an assignment to complete via email and the class is held as a 24/7 discussion board! With online universities, you are offered much more flexibility with your time, which may help you to save money, especially if you are working while attending school.
Good luck with your new career in Fire Protection Engineering!
Here are a couple of online colleges you can check out:
WPI : WPI offers all of it's courses online. They offer either a certificate or a Master in Science. Review the curriculum and see which better suits what you are looking to do with YOUR career. Always speak with a school counselor before signing up to help you find out which type of degree or certification best fits in with your goals. It is $150 per course, not including any other tech or admissions fees.
NWTC: NWTC costs $112.20 per credit hour, not including any other tech or admissions fees. NWTC offers online courses only in “Fire Alarm System Design.” These credits will go towards an associate’s degree in fire engineering. NWTC might offer a hybrid program where you can take classes at your local "brick and mortar" community college that will be equal to other required classes for the associate's program. I recommend that you speak with a counselor first before signing up first to see if this is a possibility in your area.
There are also many other factors to consider while comparing costs of an online college to a "brick and mortar" college. Weigh your options carefully!
