USU's student body grew significantly last year, Mortensen said, and the enrollment appears to be leveling off this fall.
"Last year we had a huge surge, especially in freshman," he said. "I see this year as our new base moving forward."
In a prepared statement, Utah Commissioner of Higher Education Dave Buhler said the state's colleges and universities are working hard to match continued enrollment growth with services and support for students.
"As we serve a growing number of students — we anticipate adding 52,000 students in the next decade — it will be crucial to receive legislative funding to keep higher education accessible and affordable for all Utahns," Buhler said.
Orem's Utah Valley University retained its status as the state's largest school with 34,978 students, a 5.32 percent jump from last year.
In a prepared statement, UVU President Matthew Holland said the enrollment growth is a validation of the school's hard work since its founding 75 years ago.
"Few institutions have evolved like UVU has, particularly in such a relatively brief span," Holland said. "This region has asked UVU to offer more with each passing generation to meet the needs of both a growing populace and economy, and it has always delivered and will continue to deliver."
The University of Utah, the state's flagship campus, saw a total head count of 32,061 students. It is Utah's largest school based on full-time students, with an enrollment of 27,439 compared with UVU's 23,706.
During a meeting of the University of Utah board of trustees Tuesday, Associate Vice President Mary Parker said the U.'s current freshman class, at 3,612 students, is the largest in the school's history.
Incoming freshmen at the U. also averaged a 25.11 on the ACT exam, Parker said, and a high school GPA of 3.61.
"We're really excited about that," Parker said. "As we think about recruiting the students here to the university, our Honors College is an instrumental partner."
Dixie State University saw the largest percentage growth, climbing 5.76 percent to 8,993 students and 7.38 percent in its full-time-equivalent enrollment.
Snow College remains the state's smallest higher-education institution with 5,350 students, a 4.68 percent increase over last year.
