The University of Michigan's index of consumer sentiment advanced to 83.9 from 82.7 in October, and the number of Americans filing for first-time jobless claims fell by 15,000 to 427,000 last week, surprising economists with a fourth straight weekly decline. And retail sales did bounce back big time in October, though they're still a long way from normal levels...
That’s where the “achievement index” comes into play. Developed by Valen E. Johnson, a professor of statistics at Duke University, the achievement index is a system of ranking students that takes into account how each student performs relative to the people in his course, and how the people in his course performed in their other courses. Johnson compares it to the rankings in college sports, which take into account the difficulty of the schedule in addition to the team’s record. The Harvard football team is a great team...
With the achievement index, a B in a course where many C’s are given out, would be worth more than the same B in a class where everyone gets an A or a B. And that B would be worth even more to students’ ranks if their classmates did very well in other classes. This way there would be no incentive to find classes with easy graders. Rather, students would be encouraged to take courses that challenge them, and then be compensated by this system for the risk involved...

Though Fitzsimmons could not release Harvard’s AI index for any particular class year, he did mention that all of Harvard’s athletes fall well within one standard deviation (in other words, a 16 to 17 percent fluctuation) of the total student body...
Despite this seemingly large number of prospective students, Murphy points to the Ivy-best AI index as proof that “Harvard Football has the smallest pool of football recruits in the nation because we have the highest academic standards in the nation...
