Common questions

Can I take classes if I'm working full-time?
Yes. At least one student completed HVAC certification while working full-time as a correctional officer, so the schedule accommodates working adults.
Do I get hands-on practice or just videos?
Both. Courses include weekly videos taught by instructors plus four hours of hands-on lab practice each week with an instructor present.
Can I take classes in Spanish?
Yes. NTI offers at least the electrical technician course taught in Spanish.
