Not only was she the first woman to be elected to the School Board, she was also one of the longest-serving members of the board. She was elected several times to serve as President of the School Board, becoming the first woman to have that title. During one of her terms, plans to construct Little Rock High School (now Central) and Dunbar High School (now Dunbar Middle School) were finalized.
In her capacity as President, she had to sign contracts. She became the first woman in the country to sign a multi-million dollar contract for a public building project. McDermott Elementary is named in her memory.
