AUSTIN — Officials have decided against a full investigation despite a preliminary inquiry finding that the friends and family of state lawmakers are getting special admissions consideration from the University of Texas at Austin.

Applicants for admission as a freshman were nearly four times as likely to be admitted as the general population if they had a legislator appeal directly to University President Bill Powers, an investigation by the chancellor’s office has found.

Fully a quarter of the politically connected applicants to UT’s School of Law were admitted despite grade point averages and Law School Admission Test — LSAT — scores “well below” and “far below” the usual standards. These students produced four of 10 of the worst LSAT scores among all students admitted since 2009, the report found.
