In all, at least 53 students who graduated from Trezevant shouldn’t have received their diplomas, according to Stanton’s report.

After Stanton’s presentation, the school board voted unanimously to fire former football coach Teli White, who has been suspended since June pending the investigation’s outcome. But board members left the door open to other possible dismissals later.

“We know there were people who were in that building for quite some time …,” said board member Chris Caldwell. “I think it’s worth looking into because those people may be in other positions in authority.”

Stanton recommended that the district create an alert system when transcripts are changed digitally and a uniform policy on grade minimums that contributed to students being “unduly advanced” to the next grade. He also urged the district to require monthly reports from principals explaining any transcript changes and to regularly audit such changes.

District leaders report that, this year, it already has conducted special trainings of school personnel with access to grades and invested in new software and personnel to oversee the data.

Board members called the findings of the investigations troubling, especially after Hopson assured them in June that possible grade-changing issues were isolated to Trezevant based on the evidence at that time.

“We have to all know and understand that we have royally messed over some of these children in this district, especially when we pass them and gave them a diploma when we knew — we knew — they were not eligible to graduate. So, I hope that this report is a lesson to us all,” said Stephanie Love, whose district includes Trezevant High.

Before becoming principal of Trezevant High School in 2016, Ronnie Mackin was principal at Raleigh Egypt Middle School, both in Memphis.

Lawyers hired to investigate Mackin’s subsequent allegations — including that he was being targeted for dismissal because of alleged financial fraud at Trezevant — found no basis for that claim.

Reached by Chalkbeat later Tuesday night, Mackin did not immediately comment on the findings.

Dixon Hughes Goodman was hired to review four years worth of student transcripts from all high schools in Shelby County Schools, Tennessee’s largest district. The company scanned every transcript in the district’s database to flag schools with high instances of grade changes for further investigation. The review took months longer than originally targeted.
