This study investigated relationships between high school counselors' ethical decision-making, gender, attitudes towards gender, and sexual attitudes. Of the 161 respondents, only 157 participants' data sets were included in the data set. Participants completed the Ethical Decision-Making Questionnaire, The Brief Sexual Attitudes Scale (Hendrick, Hendrick, & Reich, 2006), the Sex-Role Egalitarianism Scale (King & King, 1997) and a demographics questionnaire. Findings showed that student gender was not significant in predicting the subscales of the Ethical Decision-Making Questionnaire. Regression analyses indicated that counselor's religious affiliation, counselor age, Sex-Role Egalitarianism Scale scores, and frequency of counseling male students predict Consensual Sexuality Activity subscale scores. Permissiveness and Birth Control subscales and religious affiliation predict Sexual Activity with Victimization scores. And Instrumentality, Birth Control, and the Sex-Role Egalitarianism Scale scores predict Sexual Activity with HIV scores.
