On-line Diploma Prep Access

Having a very successful daytime course, OIC has launched an online high school equivalency/GED prep course, entitled "Diploma Prep 24/7™."  The program will deploy customized instructor-regulated coursework online to specifically target working adult learners who seek a high school diploma but are unable to attend an on-site class.

OIC’s Diploma Prep 24/7™ is a virtual classroom that meets on Saturdays via computer through a distance learning component. Student assignments are made throughout the week for follow-up instruction during the live streamed class.  The online component will include live streaming of virtual sessions, class recordings, on-demand video library content, and multi-media/screen sharing.  Enrolled students will be able to access the course from at-home computers or through a network of partner programs, which will offer computer access at their satellite locations.


If you are in need of additional help, GED tutors are available to assist in Language Arts, Science, History, and Math.
