But some university officials -- including those at UNC -- say verification requests should be considered on an individual basis or is not necessary at all.
The system was tested this year by UC-San Diego, which randomly checked a total of 437 applicants. Only one student was unable to provide the required information.
Four categories were randomly sampled -- including reported family income, participation in special programs, exceptional talents and awards, and leadership activities.
Officials began checking the information provided on applications because several pilot studies showed that some students lie about their involvement in certain activities, said UC-San Diego Admissions Director Mae Brown.
Brown said the random checks of students applications were done to appease people who questioned the application process. "It's to reassure the public ... and the students that yes, we are checking."
She added that the majority of students asked to provide evidence of their activities complied.
"We were very encouraged by the results we found," Brown said.
Brown University Admissions Officer Angela Wright said she does not think there is any reason to question all students' applications.
"If we have a particular question about a student, then we will seek independent verification on a case-by-case basis," she said.
