Harry Potter and Reading Level Data Set 14 in Appendix B lists measured reading levels for 12 pages randomly selected from J. K. Rowling’s Harry Potter and the Sorcerer’s Stone. The Flesch-Kincaid Grade Level measurements are summarized with these statistics: n 5 12, 5 5.075, s 5 1.168. Teachers at the West Park School District will not use the book unless the reading level for a typical page can be shown to be above grade 4.
