NEW BRUNSWICK, NJ — Mildred S. Scott, Middlesex County’s sheriff, has received a law-enforcement ambassador award from a New Brunswick-based group focused on diversity.

The American Conference on Diversity chose Scott, who was elected sheriff in 2011, for her long career in law enforcement and accomplishments as sheriff, according to the group. She will be honored in April during the 69th Humanitarian Awards Gala in West Orange.

Scott is the first woman to become sheriff in the county and the first African-American sheriff in New Jersey.

“Scott has made significant improvements to the management of the sheriff’s office, including undertaking the first accreditation process in the history of the Middlesex County Sheriff’s Office,” the group wrote in a press release.

Accreditation requires a “rigorous analysis” of policies and procedures, according to the release. Ten other sheriff’s offices in the state have earned the designation.

The American Conference on Diversity also praised Scott for making “substantial changes to the personnel structure” of her department and technological improvements.

Scott graduated from the county police academy in 1968 and then went to work in the sheriff’s office, according to the group. She climbed the ranks, becoming a sergeant, lieutenant, chief warrant officer and then, in 1991, chief sheriff officer.

Throughout her career, Scott supervised officers, oversaw courthouse security, launched fingerprinting programs in county schools, helped senior citizens institute a home-security initiative and coordinated the transportation of prisoners, according to the release.

After retiring in 1995, she was elected to Piscataway’s governing body. She served as a councilwoman until 2008.

She became a county freeholder in 2008.

Scott is serving her third term as sheriff. She won the seat last November.

The American Conference on Diversity awarded Scott the honor amid its celebration of Black History Month.
