Human Development & Sexual Health

The classroom is an important source of sexual health information for children and youth. 

Most girls enter puberty between the ages of 8 and 13 years, while most boys begin puberty between the ages of 9 and 14 years. Teaching accurate information about maturation and sexual health helps students to have a healthy understanding of their growth and development, to develop healthy sexual habits and to make responsible decisions.

The following resources can be used by teachers in the classroom or to support school initiatives. For questions, contact our School Health Curriculum Resource Line at 1-800-265-7293 ext. 4111 or email
