In 2015, approximately 48 states, the district of columbia, american samoa, guam, the northern mariana islands, puerto rico, and the virgin islands had statutes requiring mandated reporting of abuse by in the medical, social service, school, and law enforcement fields.

"Professionals" would seem to be the word to fill in the blank in your sentence.

The mandate specifically lists professions that have frequent contact or interaction with children, such as the professions or fields that you listed in the statement:  Medical workers, social workers, teachers or other school officials, law enforcement officers.  To that list you could also add childcare providers, and therapists or counselors.  Some states also would require workers and even volunteers in programs that provide organized activities for children, such as camps or recreation centers.

In my honest opinion , i’d say franklin d roosevelt was a president that impacted our nation , i say this because fdr is voted among top three best us presidents and he was the longest serving president by 3 terms , usually presidents only supposed to have two terms increments of 4 years , equivalent to 8 years total before election time. and he established the fdic , through the 1933 banking act and he established the us , social security system , during his presidency, and established a national minimum wage , through the fair labor standards act , fdr led the allied coalition to victory in wwii and he played a major role in the creation of the united nations.
