SCOPE OF STATUTORY EXEMPTIONS An "educational institution" as defined in RCW 28B.05.030(1) which provides educational services through workshops and seminars is not exempt from the Educational Services Registration Act solely on the basis that none of those workshops or seminars are of more than three calendar days in duration; nor is such an institution exempt because of the fact that, although it solicits from more than one business concern, it does not solicit the general public.
