One of Shelby County Schools’ top human resources officials has left the district.

As director of human capital, Sheila Redick was responsible for hiring new teachers for Tennessee’s largest district. She resigned several weeks ago to relocate with her family and has not been replaced, a district spokeswoman confirmed Thursday.

Her departure leaves a void as a new school year begins and the system seeks to hire additional teachers. Shelby County Schools, which employs about 5,800 teachers, needed about 100 more teachers when classes began on Aug. 8.

Redick joined the district in 2013 after nearly four years at TNTP, The New Teacher Project. There, she was the director of operations and communications as part of the $90 million grant from the Bill & Melinda Gates Foundation to improve teacher effectiveness in Memphis schools.
