Physical education teachers should provide a variety of age-appropriate and grade-level opportunities for students to demonstrate skill development and competency. They should not, however, use the Standard to compare students. The Standard and outcomes consider differences in cultural norms and access to resources outside of school and include alternative activities to engage students. The Standard include modifications and adaptations for students with disabilities based on the Adapted Physical Education National Standard. Physical education teachers may modify terminology when implementing the Standard to ensure that students understand the concepts. The Physical Education Glossary contains definitions for many of the terms used in the Standard and outcomes.
