SALEM — High-schoolers applying to Oregon’s public universities won’t need to submit their SAT or ACT scores anymore.

The state’s largest universities on Wednesday announced they’re joining a growing movement among institutions of higher education giving prospective freshmen the option of omitting standardized test scores from their applications. More than 1,000 four-year universities have already dropped the requirement, according to a news release.

“Standardized tests add very little to our ability to predict an individual student’s success at a university or college,” said Jon Boeckenstedt, OSU vice provost for enrollment management.

Oregon universities in their joint announcement said research showing strong ties between family income and student performance on standardized tests like the SAT and ACT played a factor in their decision. Some university systems have long had policies that cleared in-state applicants at the top of their graduating class for automatic admission and waiving the standardized testing requirement.

Robert Schaeffer, interim director at the National Center for Fair and Open Testing, said Oregon’s move was the broadest of its kind.

“We’ve certainly been keeping our eye on Oregon State and the University of Oregon, in particular,” he said.

Still, Oregon universities’ move away from making standardized test scores compulsory in their applications doesn’t mean admissions officials will outright refuse to accept them.

“Students who believe their test scores are indicative of their ability or talent are welcome to submit scores, just as they are welcome to submit any supplemental information,” University of Oregon Director of Admissions Jim Rawlins said in a release.

Southern Oregon University spokesman Neil Woolf told The Oregonian/OregonLive that prospective students may submit standardized test scores to determine placement in their initial English and math courses.

These are the universities included in the announcement:

• Eastern Oregon University

• Oregon Institute of Technology

• Oregon State University

• Oregon Health and Science University

• Portland State University

• Southern Oregon University

• University of Oregon

• Western Oregon University

All but the University of Oregon, Oregon State and Portland State had allowed undergraduates to apply without submitting scores from a standardized college entrance exam prior to this year. The lifting of testing requirements for admissions does not necessarily apply to graduate programs.
