AIM: The aim of this study was to test the differences in attitudes about sexuality expressed through ATTS statements and the reported level of religiosity among the study groups (male and female students and their parents) as well as within population under consideration (students by gender and age). METODHS: In the empirical part of this work, using quantitative methods, we tested the hypotheses identified. The methods of descriptive statistics, graphical and tabular presentation, Spearman and Pearson correlation analysis, Mann-Whitney U test, T-test, Kruskal-Wallist ANOVA test and ANOVA test have been used.Testing conducted has been made using Statistic 12 programme. Findings were adopted at 5% level of significance. RESULTS: Analysis of the degree of permissiveness obtained by the ATSS questionnaire found that the highest degree of sexual permissiveness have male pupils (44,90) whose degree of permisivness is significantly higher than the one of female pupils and both parents while stated religiosity doesn't significantly differ. Looking at the relationship between age and ATTS SCORE values in students, statistically significant relationship was determined with both male and female students. However, there is a stronger connection with male students as a higher correlation coefficient has been obtained. Comparing ATSS SCORE value it was determined that the value which male students have at the age of 14 female students reached only at the age of 16, from which one can see that permissiveness changes in time with both male and female students. In all groups (pupils, students, fathers and mothers) there has been established a statistically significant negative relationship between permissiveness and reported religiosity and in all the monitored groups there has been reported a rise of religiosity followed by a fall of ATSS SCORE value. All of the observed groups mostly do not support abortion or the existence of homosexual orientation in the society. The highest level of support of pornography and prostitution has been recorded with male students who expressed liberal attitude, while female students and parents expressed conservative opinion. Out of 13 observed ATSS statements, unified position among children and parents is shown at 10 from which one can see the existence of high impact of family environment on the permissiveness of students. CONCLUSION: Male students express the most liberal attitudes about sexuality, while at the same time they expressed the same amount of religiosity as female students and parents. The increase of students age follows the growing degree of liberalness and there is a statistically significant decrease of reported religiosity with students. In all of the monitored groups increase of reported religiosity is accompanied by ATSS SCORE value. All of the monitored groups mainly do not support abortion or the existence of homosexual orientation in society. The highest level of support for pornography and prostitution has been recorded among male students. In average, students and parents both reported a high level of liberalness. A unique attitude (of students and parents) in ten out of thirteen ATSS statements indicates the great influence of family environment.
