The Texas Education Agency is investigating over 100 teachers for possible involvement in a Houston-based cheating ring that, according to prosecutors, resulted in hundreds of people obtaining fraudulent educator licenses over the past several years.  

Out of 102 teachers being investigated, the TEA identified 15 as having worked at Houston ISD in recent years, according to a list the agency shared Wednesday morning with the Houston Landing. Thirteen of the 15 names match employees listed in the district’s October payroll records. It’s not immediately clear whether any of the 13 staffers have been disciplined or placed on paid leave.

HISD did not immediately respond to a request for comment.
