Most sexually harassing behavior is student-on-student. In "The Report Card on Gender Equity", by the National Coalition for Women and Girls in Education (NCWGE), it was reported that, of students who have been sexually harassed, 90% were harassed by other students. (NCWGE, 1997) And in their 2006 report on sexual harassment in higher education, the AAUW reported that 80% of students sexually harassed were targeted by other students.
One of the most common reasons reported for sexually harassing behavior is because the harasser thinks it is funny to do so. In their 2006 study, the AAUW found that this was the most common rationale for harassment by boys—59 percent used it. Less than one-fifth (17%) of those boys who admitted to harassing others say they did so because they wanted a date with the person. (AAUW, 2006) Other researchers assert that the "I thought it was funny" rationale is a fallacy, and the true reasons align more with that of a need to assert power and induce fear in others—more in line with bullying. These hazing behaviors develop in school, continue in high school and college, eventually moving into the workplace.
In late 2006/early 2007 a study revealed that more than 20% of all boys had been harassed by a female student. In 15% of all cases the girl admitted to sexually harassing the boy and asserted the reasons of "I thought it was funny" and "I'm not doing any harm, it's what he wanted". High schools are addressing this behaviour.
