Investigation reveals intentional student grade changes in Lexington


LEXINGTON, Texas (KXAN) — A tight-lipped investigation has finally been cracked open, answering many questions parents and students have about unapproved grade changes for upperclassmen at Lexington High School. 

The major conclusion from Tuesday’s school board meeting where three companies, including two digital forensic investigators, revealed their findings: many grades, GPAs and class ranks were changed intentionally, with the alterations coming from one computer and one set of credentials. 

Superintendent Tonya Knowlton would not say who those credentials belong to. She was adamant that there were no students involved or had any knowledge of the wrongdoing. 

Through the course of the investigation, the companies also found flaws in the protocols the school and district relied on. 

Some grade change forms were not being signed by the principal and there were two conflicting scales being used to calculate grades, which led to unintentional mistakes. 

Now that the investigation is over, Knowlton said the remainder of the semester will be used to ensure all mistakes are corrected. 

“It’s always good to have an outside person look at things and see how things can be improved but these are all new things that we will start working on immediately and get things in place so we can be the best that we can be.”

In closing remarks, the school board said they will follow additional recommendations and will audit the freshman, sophomore and junior classes to make sure those grades are also correct. 

Recommendations include:

  • establishing a protocol for manually entering grades
  • ensuring multiple sets of eyes look over those calculations
  • and writing to college advisors acknowledging possible inaccuracies within the transcripts, while reminding that each of those inaccuracies have been corrected

Knowlton said she plans to follow each of those recommendations and more.
