Four days after the University of Texas at Austin fired its student-aid director for violating university rules in the college-lender scandal, the university signed an agreement on Friday with the state’s attorney general in which it pledged to adopt a new code of conduct to govern its financial-aid office.

The agreement was based in part on the findings of an investigation into the student-aid director, Lawrence W. Burt, that prompted his dismissal. The code of conduct outlined in the agreement resembles a code that a number of other colleges and universities have pledged to observe in order to settle claims by New York’s attorney general, Andrew M. Cuomo, whose investigations of hundreds of colleges and lenders have given the controversy national attention.

In the agreement, the university denies breaking laws or even doing any of the things prohibited by the code of conduct. As a result, it will not pay restitution to any borrowers, as a number of colleges have promised to do in settlements with Mr. Cuomo.

Under the agreement, the university pledges to bar the receipt of gifts from lenders, revenue sharing with lenders, and employees’ service on lenders’ advisory boards for pay. It also vows to be honest with borrowers about loan options. While the code does not ban preferred-lender lists, it requires borrowers’ interests to be paramount in creating the lists and prohibits the lists’ manipulation by lenders seeking favorable treatment.

The code also forbids student-aid officials to directly own stock in a lending company, as Mr. Burt did, according to the university investigation.

The University of Texas’ president, William Powers Jr., said in a written statement that he hoped the agreement showed the university’s “commitment to reassuring our students and their families of the credibility of our financial-aid services.” —Andrew Mytelka
