Prompted by concern that the State of New Jersey driver's manual was too difficult for many low-skilled readers to read and comprehend, a study was conducted in which chapter 6 of the driver's manual was rewritten, lowering its readability level from grade 8 to grade 6. It was hypothesized that significant differences in comprehension would result between low ability students reading the manual in its present form and those reading it in the revised format. Comprehension of the rewritten and the original manual was compared using cloze tests developed from a passage in chapter 6. Two test forms, based on the published and the rewritten versions of chapter 6, were randomly administered to 74 ninth and tenth grade students with reading comprehension scores of 7.0 or below who had not taken driver education. Results showed that comprehension of the rewritten passage was significantly greater. Furthermore, students read the rewritten passage faster and with greater ease. (Appendixes include (1) chapter 6 as printed in the state of New Jersey Driver Manual, (2) rewritten chapter 6 from the driver manual and glossary, (3) original and rewritten passages used for the cloze test, and (4) cloze tests used for testing comprehension on original and rewritten passsage.)
