Online Courses

Our technical education programs are tailored specifically for remote access and individual learning. Programs are based on traditional 10-week university courses. Students will have access to slide decks that navigate through the material, as well as manuscripts with detailed information.

In both the individually-based as well as the for-credit institutional forms, students and instructors will hold regular 90 min review and Q&A sessions on Zoom. For individual-based courses the students will book their own Zoom calls with the instructor, while the Zoom meetings for the institutional format will be held weekly over a ten-week period. 

Assignments, grading, and final exams are offered in the institutional format. Certificates of completion are issued for the individual-based format. The technical material can be individually compiled from the topics list of any of the study areas, with one topic per week for a total of 10 topics for a full course.
