Academic dishonesty and counterproductive student behaviors are an ongoing concern in higher education. Over the years, multiple methods to promote student integrity have been proposed, including the use of honor codes. Collegiate honor systems, which make students collectively responsible for campus integrity, are sometimes paired with mandatory reporting policies, which have both advocates and critics. After a broad literature search, a review of 61 publications--ranging from academic journals to university publications and government reports--provided empirical data on college student observation and reporting of misconduct. Two preliminary findings emerged. First, honor code institutions with mandatory reporting policies appear to experience the lowest rates of student reporting--less than 2%--compared to 11% at honor code institutions without such policies, validating concerns about their effectiveness in fostering a culture of peer accountability. However, significant gaps in the data highlight the need for future research directly comparing honor code schools with and without mandatory reporting policies. Second, student responses regarding their willingness to report misconduct are unreliable predictors of actual reporting behavior as evidenced by the large difference in the percentage of students who said they would versus who actually did report misconduct.
