I used the USD Continuing Education Program to earn my CLAD certification. The program was very easy to complete as it was independent study. I worked during my off-track time and finished all four courses in three months. The work did seem a bit tedious at times. The prices were on the expensive side, as you must purchase the class and DVD's separately. However, I would rather pay more and get it over with on my own time rather than having a set schedule of times I needed to report to class. All in all it was a positive experience. Highly recommended.
