New Common Core exams will test whether a robo-grader is as accurate as a human
Millions of elementary, middle and high school students in 14 states and Washington, D.C. may have their essays graded by computers next year if initial tests of robo-grading prove to be accurate.
A multi-state consortium known as PARCC that is developing the tests said it hoped to use essay-grading software as soon as Spring 2015, when its new computerized tests are scheduled to roll out. The new tests are primarily aimed at assessing whether students are learning new Common Coreeducation standards, but test administrators are also experimenting with new testing technologies.

“One benefit of computerized scoring is you can get scores back sooner and it drives down costs,” explained Laura McGiffert Slover, chief executive officer of PARCC Inc., a non-profit that stands for Partnership for Assessment of Readiness for College and Careers. It is coordinating the development of new assessments for 14 states* plus the District of Columbia.
McGiffert Slover talked about computerized grading in a telephone briefing with reporters on March 20. Beginning Monday, PARCC will administer trial versions of the new tests to 1 million students, who will be asked to answer not only multiple choice questions but also write open response answers and essays. These sentences and essays will graded by humans. But the human grades will be used to “teach” the computers how to mark essays.

Jeff Nellhaus, director of policy, research and design at PARCC, explained that you need to have papers that have been scored by humans to calibrate the machines. Afterwards, the calibrated machines will grade additional essays to make sure the computer marks approximate human marks. If the computers pass that test,
College students bypassing degrees on purpose
Kevin Floerke has been down this route before. A student at Santa Rosa Junior College in Northern California, Floerke, 26 years old, already graduated in 2010 from UCLA, where he majored in archaeology. This time, however, he’s not after a degree. He’s just trying to master a set of techniques and technologies that will help him verify the details he finds while doing fieldwork. “I’m really there
