Westbury High School Principal Jason Catchings faces the prospect of being fired after an internal investigation confirmed he ordered students’ grades to be changed.

The school board is expected to vote on the termination Thursday, according to the public meeting notice. Superintendent Terry Grier‘s administration has made the rare recommendation to fire the principal, rather than agree to a buyout or settlement package, though negotiations still may take place before the board vote.

Catchings attorney, Tiger Hanner said his client doesn’t deserve to be ousted. “When the facts all come out, it will be clear that he followed the advice and directives given by his supervisors,” Hanner said, declining to disclose details. “There’s absolutely no basis to terminate his employment.”

The district’s investigative report, released last week, found that a long-term substitute teacher at the southwest Houston campus assigned failing grades to most students in an elective course, yet Catchings ordered the grades changed to an 80, or a B. Catchings told the district’s auditors that he questioned the validity of the low grades – some in the single digits – and no certified teacher was available to verify their accuracy.

“The principal stated he assigned the grades in question as he did not believe students should be penalized as a result of the matter,” the audit report said.

Texas law says that grades issued by a classroom teacher are “final and may not be changed unless the grade is arbitrary, erroneous, or not consistent with the school district grading policy.” It also says that teachers cannot be required to assign a minimum grade to a student “without regard to the student’s quality of work.”

Since issuing the Westbury report, auditors with the Houston Independent School District have begun investigating allegations of grade changes at Reagan High School based on a tip. Gayle Fallon, president of the Houston Federation of Teachers union, said she passed along a complaint from a teacher to the district.

Catchings, who has not spoken publicly about the audit, became principal of Westbury this school year after leading Scarborough High School for three years. At Westbury, he was charged with turning the school into a model Advanced Placement campus, where all students would take at least one of the high-level courses.

The board also plans to vote on resignation settlement packages with Yates High Principal Donetrus Hill and Kashmere High Principal Amber Williams, according to the meeting notice.
