Knoxville (WVLT) - There are new developments in the case against a Powell High School assistant principal.
Kimberly Kallenberg passed a polygraph test and her attorney Greg Isaacs has submitted the results to the Knox County School Board, demanding they reinstate her.
Kallenberg was placed on administrative leave earlier this year when she was accused of grade fixing.
Kallenberg says instead of being paid to sit at home, she wants to get back to work with the students at Powell.
Attorney Charles Swanson is representing Superintendent Charles Lindsey, he tells WVLT he's evaluating tons of material the school district sent to him and he's not in a position to comment.
Thursday's news brings this case out of a five month lull.
Kallenberg has denied charges against her from the beginning.
