Identify one key area that the CDC Teaching Exam A assesses.

The CDC Teaching Exam A emphasizes the understanding of epidemiology and public health principles because these areas are foundational to effective health education. Grasping the concepts of epidemiology allows educators to assess public health trends, understand disease distribution, and recognize risk factors that affect community health. This knowledge enables educators to teach students about disease prevention and health promotion in an informed and evidence-based manner, ultimately leading to better health outcomes. By focusing on public health principles, educators can incorporate vital information into their teaching that promotes awareness and encourages healthy behaviors among students and the community.
