The SE Professional Training curriculum is delivered through a combination of lecture,demonstration, and guided practice sessions with other students. Course material is taught in 8 training modules of 4 to 6 days in length, spaced out over 2½ to 3 years. Training modules must be taken in sequence. In exceptional cases, where a student is unable to attend one of the live training modules, we offer supplemental DVD training modules for our Beginning and Intermediate classes so that students may continue with their local training group (certainrestrictions may apply).
