Goble, who owned Teach Them To Read in Conyers, Georgia, pleaded guilty Wednesday to one count of conspiracy to pay bribes in connection with federal program funds.
Authorities say Goble paid bribes to former superintendent Harvey Franklin for him to influence the school board to use the $1.4 million reading program.
Franklin pleaded guilty in August 2012. He's serving more than six years in prison.
In addition, Goble was ordered to pay $1 million in restitution to the U.S. Department of Education and sentenced to three years supervised release following her term of imprisonment.
