TYLER — Officials at UT Tyler are promising to make changes in their scholarship program after numerous international students recently had their full Presidential Fellows scholarships withdrawn. University staffers say the problem arose when demand for the financial packages drastically exceeded what was anticipated. The case has now drawn attention in national higher education publications, and UT Tyler spokesman Lucas Roebuck says the university is working hard to see that it doesn’t happen again. He earlier noted that students who had their scholarships canceled were offered alternative packages, though it’s unclear how many will accept them. Roebuck points out that none of UT Tyler’s 137 Texas Presidential Fellowships were affected. Roebuck says he understands the concerns of the affected students and how important it is for them to receive a quality higher education.
