She received a Bachelor's degree in economics and went on to earn a Master’s degree in Social Foundations of Education in 1950 at New York’s Columbia University after being unable to attend the University of Georgia because Black students weren’t admitted at the time.

King Farris received a second Master’s degree in special education and taught elementary school before returning to Spelman as an educator and director of the Learning Resources Center until her retirement in 2014 after 56 years.
