Service & Training

RV Technician Distance Learning Program

The program consists of 13 on-line, non-credit courses that will provide the student with knowledge of basic troubleshooting, repair and maintenance procedures for a career at an RV dealership or service facility.

How does it work?

Each lesson will follow the textbooks published by RVIA. Students will log onto the Northampton Community College website (username and password provided after registering for the course) and work primarily on their own but have regular discussions and interactions with the instructor and other students in one of the Discussion Forums.

Additionally, students will be required to make contact with an existing RV dealer or aftermarket service center for assistance in passing the “hands-on” assignments.

There is no need to be online at any specific time of day – that schedule is up to the student; however students will need to complete coursework and quizzes by the required deadline.

After successfully completing a course, the student will receive a certificate of completion from the college.
