Schools with questionable CRCT results

By Heather Vogell

The Atlanta Journal-Constitution

Scores climbed or dipped dramatically at 12 schools in Atlanta and one in Fulton County. The AJC compared each class’ score in 2008 with its score in 2009, in the next grade.

Standard deviation shows how unexpected a score change is. The odds of a 4 standard deviation change are less than 1 in 31,000. The odds of a five standard deviation change are less than 1 in 3 million. The odds of a six standard deviation change are less than 1 in a billion.

Standard deviations	Odds it could occur naturally
4	1 in 31,000
5	1 in 3 million
6	1 in a billion
