Iowa State University in Ames ranks in the top ten in the enrollment of National Merit Scholars among the nation’s public universities. National Merit Scholars are chosen in part based on test scores from the college entrance exams taken by high school students in their junior year. I-S-U Admissions Director Marc Harding says the university enrolled 116 new Merit Scholars last year. That ranks Iowa State 7th among public universities nationally and 19th among all colleges for enrolling new National Merit Scholars. Harding says I-S-U offers scholarships that target the Merit Scholars. He says they also have to work hard to sell the school, as these students have the pick of any school in the nation.Among other Iowa schools, Grinnell enrolled 37 new National Merit Scholars; the University of Iowa had 32; Luther College enrolled six; Drake University enrolled five and Maharishi University enrolled one.
