Colorado Cheating? According to Ed News Colorado, about 35 high school students figured out how to go into their teachers' computer system. They changed their grades on instant "mastery tests" to make it look as if they'd entered the correct answers in the first place. Thirty-five kids in a major urban school district is proportionally small, but keep in mind that the mastery test is a low-stakes, formative assessment. As high-stakes standardized tests become digitized, is this something we're going to see happen more often?
