PDHPE teaches students the knowledge, skills, and attitudes needed to lead healthy, active lives and play a responsible role in society. It does this through five essential skills - communicating, decision making, interacting, moving, and problem solving - which are applied across different strands so students can use them effectively now and in the future. PDHPE is important as it encourages self-understanding and respect for others, promotes physical activity, and emphasizes informed decision making.
