When Buffalo school board members learned that Yamilette Williams lacked certification to serve as chief of curriculum, they fired her.
Williams, claiming breach of contract and defamation, sued the board in federal court.
U.S. District Judge Frank P. Geraci Jr. dismissed Williams' suit last week and pointed to a lack of evidence to support her allegations.
Now living in Florida, Williams was fired as Buffalo's academic chief in 2014 when it was revealed she did not have the required state certification. At the time, state education officials said Williams had a conditional certificate to serve as a principal, not as a district-wide administrator, in New York State.
