Every attendee that successfully completes a WZ seminar receives a certificate of attendance. WZ instructors do not pass out the certificates at the start of a seminar, they pass out the certificates at the end of the program and personally thank each attendee. Attendees must be present for at least 90% of the seminar to receive a certificate.
These certificates do not certify expertise in the techniques taught at the seminar. These certificates indicate an attendee completed the training program. WZ offers post seminar exams for employers who wish to verify the information an attendee has learned and retained. These tests can be purchased for individual attendees or licensed to organizations that wish to test employees in greater numbers.
