Potter Has Limited Effect on Reading Habits

According to the National Assessment of Educational Progress, a series of federal tests administered every few years to a sample of students in grades 4, 8 and 12, the percentage of kids who said they read for fun almost every day dropped from 43 percent in fourth grade to 19 percent in eighth grade in 1998, the year “Sorcerer’s Stone” was published in the United States. In 2005, when “Harry Potter and the Half-Blood Prince,” the sixth book, was published, the results were identical.
