Meaning of AP®

• AP stands for Advanced Placement, a program allowing high school students to take college-level courses and potentially earn college credit.
• Thousands of AP teachers have contributed to the principles espoused in the program.

Principles of AP®

1. Clarity and Transparency:
      - Teachers and students deserve clear expectations; all frameworks and assessments are made public.
2. Encounter with Evidence:
      - AP courses engage students with evidence and the scientific method, fostering independent thinking.
3. Opposition to Censorship:
      - AP relies on intellectual freedom for teachers and students; banning crucial topics results in loss of AP designation.
4. Opposition to Indoctrination:
      - Critical assessment of opposing viewpoints is encouraged; students are not required to conform to any specific perspective.
5. Respect for Diverse Perspectives:
      - AP promotes equitable access to diverse histories and cultures through grounded studies.
6. Valuing All Student Contributions:
      - Every student's engagement with evidence is respected, and a respectful debate is encouraged.
7. Choice for Enrollment:
      - AP courses are a choice freely made by students and parents, with clear descriptions available online.
