Women are also underrepresented in the administration and this is because there are so few women full professors. In 1985,Regent Beryl Milburn produced a report blasting(轰动)the University of Texas System administration for not encouraging women.The University was rated认为 among the lowest for the system.In a 1987 update ,Milburn commended the progress that was made and called for even more improvement.

One of the positive results from her study was a System-wide program to inform women of available administrative jobs.

College of Communication Associate Dean Patrica Witherspoon,said it is important that woman be flexible when it comesto relocating if they want to rise in the ranks.

Although a woman may face a chilly climate on campus , many times in order for her to succeed , she must rise above the problems around her and concentrate on her work.

"If they do that will be successful in this system.If they spend their time in little groups mourning the sexual discrimination that they think exists here, they are wasting valuable study time."
