• Opportunity to earn college credit, advanced placement, or both while still in high school.
• AP courses in 40 subjects, each culminating in a challenging exam.
• Students learn to think critically, construct solid arguments, and see many sides of an issue.
• AP courses demonstrate to college admission officers that students have sought the most challenging curriculum available to them.
• Students who score a 3 or higher on an AP Exam typically experience greater academic success in college and are more likely to earn a college degree than non-AP students.
• Each AP teacher’s syllabus is evaluated and approved by college faculty.
• AP Exams are developed and scored by college faculty and experienced AP teachers.
• Most four-year colleges and universities in the United States grant credit, advanced placement, or both on the basis of successful AP Exam scores.
• More than 3,300 institutions worldwide annually receive AP scores.

AP Course Development

• AP courses and exams emphasize challenging, research-based curricula aligned with higher education expectations.
• Individual teachers design their own curriculum, selecting appropriate college-level readings, assignments, and resources.
• The course and exam description presents the content and skills that are the focus of the corresponding college course and that appear on the AP Exam.
• Content and skills are organized into a series of units that represent a sequence found in widely adopted college textbooks.
• The intention of this publication is to respect teachers’ time and expertise by providing a roadmap that they can modify and adapt to their local priorities and preferences.
• The AP Program is able to provide teachers and students with formative assessments—Progress Checks—that teachers can assign throughout the year to measure student progress as they acquire content knowledge and develop skills.

Enrolling Students: Equity and Access

• The AP Program strongly encourages educators to make equitable access a guiding principle by giving all willing and academically prepared students the opportunity to participate in AP.
• Encourage the elimination of barriers that restrict access to AP for students from ethnic, racial, and socioeconomic groups that have been traditionally underserved.
• All students should have access to academically challenging coursework before they enroll in AP classes, which can prepare them for AP success.

Offering AP Courses: The AP Course Audit

• Each school implements its own curriculum that will enable students to develop the content understandings and skills described in the course framework.
• Schools wishing to offer AP courses must participate in the AP Course Audit, a process through which AP teachers’ course materials are reviewed by college faculty.
• The AP Course Audit was created to provide teachers and administrators with clear guidelines on curricular and resource requirements for AP courses and to help colleges and universities validate courses marked “AP” on students’ transcripts.
• This process ensures that AP teachers’ courses meet or exceed the curricular and resource expectations that college and secondary school faculty have established for college-level courses.
• The AP Course Audit form is submitted by the AP teacher and the school principal (or designated administrator) to confirm awareness and understanding of the curricular and resource requirements.
• A syllabus or course outline, detailing how course requirements are met, is submitted by the AP teacher for review by college faculty.

How the AP Program Is Developed

• The scope of content for an AP course and exam is derived from an analysis of hundreds of syllabi and course offerings of colleges and universities.
• A committee of college faculty and expert AP teachers articulate what students should know and be able to do upon the completion of the AP course.
• The resulting course framework is the heart of this course and exam description and serves as a blueprint of the content and skills that can appear on an AP Exam.
• The AP Test Development Committees are responsible for developing each AP Exam, ensuring the exam questions are aligned to the course framework.
• The AP Exam development process is a multiyear endeavor; all AP Exams undergo extensive review, revision, piloting, and analysis to ensure that questions are accurate, fair, and valid, and that there is an appropriate spread of difficulty across the questions.

How AP Exams Are Scored

• The exam scoring process relies on the expertise of both AP teachers and college faculty.
• Multiple-choice questions are scored by machine, while the free-response questions and through-course performance assessments are scored by thousands of college faculty and expert AP teachers.
• All AP Readers are thoroughly trained, and their work is monitored throughout the Reading for fairness and consistency.
• A highly respected college faculty member serves as Chief Faculty Consultant and maintains the accuracy of the scoring standards.
• Scores on the free-response questions and performance assessments are weighted and combined with the results of the computer-scored multiple-choice questions, and this raw score is converted into a composite AP score on a 1–5 scale.
• AP Exams are not norm-referenced or graded on a curve; they are criterion-referenced.

Using and Interpreting AP Scores

• The extensive work done by college faculty and AP teachers in the development of the course and exam and throughout the scoring process ensures that AP Exam scores accurately represent students’ achievement in the equivalent college course.
• Frequent and regular research studies establish the validity of AP scores.

Becoming an AP Reader

• Each June, AP teachers and college faculty evaluate and score the free-response sections of the AP Exams.
• Ninety-eight percent of surveyed educators who took part in the AP Reading say it was a positive experience.
• Opportunities to bring positive changes to the classroom, gain in-depth understanding of AP Exam and AP scoring standards, receive compensation, score from home, and earn Continuing Education Units (CEUs).
