The Texas Records Exchange (TREx) system is a web-based software application designed for the exchange of electronic student records as mandated by the 79th Legislature, 3rd Called Session, 2006 (House Bill 1).  By using the TREx application, school registrars have the capability to electronically request and receive student records for students who have attended or will be attending Texas public schools.  High school registrars and counselors also have the capability to electronically create and send official student transcripts to Texas public colleges and universities using TREx to access the University of Texas (UT) SPEEDE server.
