Health Education in Schools

School-based health education helps adolescents acquire functional health knowledge, and strengthens attitudes, beliefs, and practice skills needed to adopt and maintain healthy behaviors throughout their lives.

Schools can play a critical role in reducing adolescent health risks through the delivery of effective health education.1-3

The specific content and skills addressed in health education, including sexual health and other related topic areas (e.g., violence prevention, mental and emotional health, food and nutrition), are commonly organized into a course of study or program and often summarized in a curriculum framework.

Health education curriculum should include:

A set of intended learning outcomes or objectives that directly relate to students’ acquisition of health-related knowledge, attitudes, and skills.

A planned progression of developmentally appropriate lessons or learning experiences that lead to achieving health objectives.

Continuity between lessons or learning experiences that clearly reinforce the adoption and maintenance of specific health-enhancing behaviors.

Content or materials that correspond with the sequence of learning events and help teachers and students meet the learning objectives.

Assessment strategies to determine if students have achieved the desired learning.

Health education is effective at addressing adolescent behaviors

Youth behaviors and experiences set the stage for adult health.1-3 In particular, health behaviors and experiences related to early sexual initiation, violence, and substance use are consistently linked to poor grades and test scores and lower educational attainment.4-7 In turn, providing health education as early as possible can help youth to develop positive well-being, academic success, and healthy outcomes into adulthood.

Health education tends to be more effective when it is taught by qualified teachers, connects students to health services, engages parents and community partners, and fosters positive relationships between adolescents and adults who are important to them.

Research suggests that well-designed and well-implemented school health programs can influence multiple health outcomes, including reducing sexual risk behaviors related to HIV, sexually transmitted diseases (STDs) and unintended pregnancy, decreasing substance and tobacco use, and improving academic performance.8-10

National Health Education Standards

The National Health Education Standards were designed to establish, promote, and support health-enhancing behaviors for students in all grade levels – emphasizing planned, sequential learning from Pre-K through grade 12. The standards outline what students should know and be able to do by grades 2, 5, 8, and 12, serving as a valuable tool for schools in designing or selecting effective health education curricula.11

Sexual health is a critical component of health education

School-based sexual health education provides youth with the knowledge and skills they need to protect their health and become successful learners. Increasing the number of schools that provide health education on key health risks facing youth, including HIV, STDs and unintended pregnancy, is a critical health objective for improving our nation’s health.12

National Sex Education Standards

The National Sex Education Standards outline foundational knowledge and skills students need to navigate sexual development and grow into sexually healthy adults. The standards are designed to help schools focus on what is most essential for students to learn by the end of a grade level or grade span and can be used to create lessons and curricula with aligned learning objectives.13
