U.S. Students Get Top Scores for Sleepiness

In both the Trends in International Mathematics and Science Study and the Progress in International Reading Literacy Study, the percentage of U.S. pupils enrolled in classrooms in which teachers report that student sleepiness limits instruction “some” or “a lot” in 4th grade reading and 4th and 8th grade math and science has consistently exceeded 70 percent. Internationally, overall averages for sleepiness range from 46 percent to 58 percent, depending on the grade level and the subject. (Eighth grade science classes were the “sleepiest.”)
