Answering your graduation rate questions—sort of.
I am frequently asked what the U.S. dropout rate is. That’s like asking how you make chocolate ice cream; there are so many possible methods and outcomes. It is easy for me to make recommendations when it comes to ice cream: Alton Brown if you have a lot of time or David Lebovitz if you don’t. Graduation rates, however, are more complicated.
Today NCES released its most recent calculations of graduation and dropout data, taken from the Common Core of Data. The dropout rate—the percentage of students enrolled in 2006-07 who were not enrolled in 2007-08 and had not completed school—was 4 percent. The average freshman on-time graduation rate—the percentage of high school students who entered ninth grade in 2004 and graduated in 2008—was 75 percent, up from 74 percent the previous year. Keep in mind that this doesn’t count the real people who entered school and graduated. It just compares the total number of students at the start to the number at the finish line. If 100,000 students drop out sophomore year and 100,000 exchange students from Belgium arrive junior year and get diplomas, that’s considered a wash. And having 4 percent of students drop out each year leaves more than 75 percent left to graduate, yes?
There are other wishy-washies you can read about in the methodology section. They are sort of inevitable, I guess, until we have data systems that actually track individual students. But the info we do have is still worth paying attention to. Take a look; you might find something intriguing. Like, why is ninth grade such a flashpoint for dropping out in Louisiana, as opposed to the later grades in other states?Or depressing: Why do practically half of your students fail to graduate on time, Nevada? I do wonder if some of the variation between states can be attributed to reporting issues rather than simply who does better or worse by its students.
P.S. to Vermont and South Carolina reporters: Your states were missing from the some of the counts because of missing data. Why don’t you find out what’s up with that?
