2. Partying and tardiness on the wane
The percentage of students who spent time partying during the week in their senior year of high school declined from nearly 70 percent in 2009 to just over 65 percent in 2011.
The percentages who drank occasionally or frequently also went down a few points in recent years, with about 41 percent drinking wine or liquor and just over 35 percent drinking beer. In the late 1970s and early ’80s, more than 70 percent reported frequent alcohol use.
Fewer students say they came late to class as high-school seniors: 54.7 percent, compared with 57.5 percent in 2010.
