Journalism educators train students on Associated Press (AP) style, helping them navigate grammar, accuracy, and ethical issues. However, there is little peer-reviewed research testing which methods are most effective. This article used a quasi-experimental pretest/posttest methodology over six semesters to test three common methods: timed, closed-book, in-class quizzes; timed, open-book, in-class editing exercises; and take-home exercises. No one method proved statistically superior. All types moved students from high Fs to Cs. This study showed that learning AP style needs constant reinforcement.
