“Continued strong enrollment and increased retention demonstrate Illinois State’s commitment to student success and exceptional student experiences,” said President Aondover Tarhule. “The Redbird approach to collaborative teaching, scholarship, and service is the University’s proud legacy and its future.” 

The improvements in enrollment and retention result from a focused effort to improve the Redbird experience through new programs that meet student and employer expectations, as well as expanded student support resources and engagement opportunities. 

Executive Director of Admissions and Recruitment Marketing Jeff Mavros is especially pleased with the strong enrollment in new academic programs, including Illinois State’s new College of Engineering, data science, and sports communication. Furthermore, the academic profile of Illinois State’s incoming freshman class continues to improve with an average GPA of 3.63/4.0. The incoming class also includes 527 new students in the Honors Program, a record for the second year in a row. 

“Our growing application pool reflects increasing interest in Illinois State, and the rise in student retention shows that our student success initiatives are effective,” said Mavros. “We look forward to the many achievements of our newest Redbirds.”
