Most standardized tests are multiple-choice. Why? Because they are simply easier to score by machine. How could millions of essays be evaluated fairly by computer programs? The William and Flora Hewlett Foundation is trying to come up with an answer to that question by creating a $100,000 competition for software that can accurately grade essays. The Foundation is hoping to find software that can evaluate like humans. In the competition, companies that already have developed essay evaluators will be grading 19,000+ essays, which will be matched against grades given by teachers. Others, both individuals and companies, who do not have ready-to-go essay evaluators, may also vie for the prizes by creating their own programs.
