I feel that those professions that are key to public health, serve a number of citizens in their role and whose technical aspects are unable to be judged by the public should have continued oversight as to their proficiency.  That would include roles such as wastewater management facility operators, wetland delineators and soil scientists should continue to be overseen. 

The others are usually one on one relationships, and are ones that can be terminated if the relationship is not working out; the customer does not like their work; or a second opinion is easily obtained. Also, they are often small business people that don't need the overhead of regulation. Or, in the case of common interest community managers are employed by a Board of Directors who can judge the quality of their work and terminate unsatisfactory ones. 

Thank you for the opportunity to offer input.
