I am a licensed community-association manager.  This requirement has not affected my competency, professionalism or honesty in any way.  And I know of no manager's whose competency has been increased by this law.  In my 23rd year of successful management, I was required to take beginning-level courses, which bored me to no end, and I had to pay unnecessary fees.  The classes alone cost me $495.00.  I passed the state test.  Took me 19 minutes to complete. It had been predicted that this law would result in a dearth of managers, and that has happened.  I see no reason to keep the law.

The real problem with common-interest communities is the boards, or, more specifically, the directors on those boards.  They are the ones who make the decisions, not the managers.  The managers usually just do as instructed.  What is needed is some way to hold directors responsible for their actions. 
Also, what is needed is a mandatory and binding dispute-resolution process to settle disputes.
