80% of social work nation wide has adopted a similar rule in order to protect the public.  The MSW graduate is a social worker, and therefore, the public have a right to expect  certain levels of skill and competence and feel secure in that knowledge.  Some people object to this change on the basis of the ASWB exam, which has been shown to be biased against people of color.  I see these as equal but separate issues, and because I know that the exam is being examined and will be changed, I support the rule change on its own.
