The purpose of this study was to determine if any significant differences existed in the achievement scores of students who complete a business report writing course in an individualized instruction method as compared with those students who complete the same course in a traditional teacher-lecture method. Five hypotheses were analyzed for differences. A t-test procedure was used to compare each teacher's individualized section with his traditional section to determine if any significant differences existed. The results showed that the individualized method of instruction obtained significantly higher scores than the traditional teacher-lecture method on the final objective examination. The individualized-method students performed equally as well on the final written examination as the traditional-method students. When the experimental sections were compared, it was found that different teachers had a significant effect on the students' performance for the final written examination but not on the final objective examination. The results for the traditional sections indicated that the different teachers in the study had a significant effect on the students' performance for both the final objective and written examinations.
