I do not understand why the board would consider not requiring plumbing heating and mechanical contractors to take continuing  education training.  These trades are no less important than electrical.  I personally think Builders should be required to take CEU training as well.  I have been in the inspecting business for nineteen years and the most common comment we get when we turn a job down is, "when did that change".  The CEU training primarily covers code changes which all tradesmen need to keep up with.  The public would be surprised to know that most of the tradesmen don't even have a current code book.
