This report begins with a history of the implimentation of family life education in public schools in Canada in the late 1960s and early 1970s and a review of studies of parental attitudes towards the policy. Research shows in general that sex education does not promote promiscuity; rather it favors more responsible behavior. The success of sex education programs that have included the parents themselves is affirmed. The present survey of 130 mothers of school children in grades 6 (39%) 9 (33%) and 12 (28%) in a school district in Ontario found that most supported the teaching of sex education but were divided about which values should be taught. 83% of the sample was between 30 and 45 years of age. The mean age was 40. 45% had some university education and 33% had finished high school. 89% were married. 69% were Protestant 9% Catholic and 14% reported no religion. 28% attended church once a week or more. A table shows the pattern of answers to a series of 18 questions dealing with sex education and premarital sex. Whereas 1/2 disapproved of premarital sex only 1/3 believed that the important objective of sex education should be to discourage premarital sex. Nevertheless the strongest variable relating both attitudes toward the teaching of sex education and values in sex education was that of premarital sexual attitudes. Church attendance was not related to support for sex education but was related to the teaching of conservative values. These results clearly indicate the necessity for educators to be aware not only of whether parents support sex education but also of the values which they want to have presented.
