Classes are scheduled to start in Fall 2025.

Taking Our Online Courses

Tools are essential for completing hands-on skills training especially for our online classes. You can purchase our technician's toolkit or purchase tools on your own. Please ask for our checklist so that your tool purchases meet class requirements. With our toolkit, you’ll be equipped for your first job on day one. If you order our toolkit, please allow 4-6 weeks for delivery.

All online students must attend an orientation before the first day of class. This will help you become familiar with our video conferencing tools and confirm you have all required equipment for the class.

To see what’s included in our kit, visit our Online Toolkit section to view the basic course equipment. You will also need an OTDR to learn advanced testing methods. See the tool below. Both the toolkit and OTDR are needed for this class.
