MONTEREY, CALIF., April 22, 2014—Advances in technology have enabled students to access the

Internet at any time, from anywhere, on any device. The availability of an abundance of online content

means plagiarism is easier than ever. Pacific Metrics Corporation (www.pacificmetrics.com), a leading

provider of education technology solutions, is working to solve the issue of plagiarism in online

assessment. Using its expertise in research and assessment, Pacific Metrics has developed a

computer-based method for detecting plagiarism in an assessment environment, for which it was

awarded a new patent from the U.S. Patent and Trademark Office.

The patent provides a system for quickly and precisely detecting student-to-student copying through the

computer-based evaluation of similarities of student responses to open-ended test items. This detection

method flags student responses to open-ended assessment items that are similar enough to suggest

potential instances of student-to-student copying. Similarity statistics gathered via the plagiarism

detection tool can be used to identify more widespread or systematic instances of cheating and can be

used as a powerful mechanism in a large-scale assessment environment. This invention can support

any electronically delivered constructed response in any industry. This system was invented by Sue

Lottridge, Ph.D., Director of Machine Scoring, Pacific Metrics; Howard C. Mitzel, Ph.D., former CEO,

Pacific Metrics; and John A. Pennington. The patent was filed in September 2009 and was awarded to

Pacific Metrics in November 2013.

“Pacific Metrics remains fully committed to improving learning and assessment through advances in

next-gen research and technology solutions,” said Bob Guerin, acting CEO of Pacific Metrics. “This

patent reinforces our commitment to innovation—we’re very, very proud of our Research team for this

important contribution and accomplishment.”
