Barton Community College and higher learning institutions across the nation continue to battle what Vice President of Instruction Elaine Simmons calls “professional cheaters.”The five students expelled from Barton campuses this semester for academic integrity issues were doing a lot worse than hiding crib sheets in their clothing before taking tests, apparently. But college officials are onto them.Two years ago, the college started using biometric identification software to make sure online students are actually doing their own coursework and not paying someone else to sit in on classes and tests.As for the more traditional types of cheating, they have been going on in high schools and colleges for years. The International Center for Academic Integrity reports that over 12 years, between the fall of 2002 and the spring of 2015, 71,300 university undergraduates were asked about cheating and about 68 percent of them admitted to doing so at least once.
