Course Content
This course framework provides a clear and detailed description of the course requirements necessary for student success. The framework specifies what students must know, be able to do, and understand, with a focus on core principles and theories of the discipline. The framework also encourages instruction that prepares students for advanced chemistry coursework.
The AP Chemistry course framework is organized into nine commonly taught units of study that provide one possible sequence for the course. As always, you have the flexibility to organize the course content as you like.
| Unit | Exam Weighting (Multiple-Choice Section) |
|---|---|
| Unit 1: Atomic Structure and Properties | 7%–9% |
| Unit 2: Compound Structure and Properties | 7%–9% |
| Unit 3: Properties of Substances and Mixtures | 18%–22% |
| Unit 4: Chemical Reactions | 7%–9% |
| Unit 5: Kinetics | 7%–9% |
| Unit 6: Thermochemistry | 7%–9% |
| Unit 7: Equilibrium | 7%–9% |
| Unit 8: Acids and Bases | 11%–15% |
| Unit 9: Thermodynamics and Electrochemistry | 7%–9% |
Science Practices
The AP Chemistry framework outlines distinct skills, called science practices, that students should practice throughout the year—skills that will help them learn to think and act like chemists.
| Skill | Description | Exam Weighting (Multiple-Choice Section) | Exam Weighting (Free-Response Section) |
|---|---|---|---|
| 1. Models and Representations | Describe models and representations, including across scales. | 8%–12% | 2%–4% |
| 2. Question and Method | Determine scientific questions and methods. | 8%–12% | 10%–16% |
| 3. Representing Data and Phenomena | Create representations or models of chemical phenomena. | Not assessed in multiple-choice section. | 8%–16% |
| 4. Model Analysis | Analyze and interpret models and representations on a single scale or across multiple scales. | 23%–30% | 5%–9% |
| 5. Mathematical Routines | Solve problems using mathematical relationships. | 35%–42% | 43%–53% |
| 6. Argumentation | Develop an explanation or scientific argument. | 8%–12% | 15%–24% |
AP and Higher Education
Higher education professionals play a key role in developing AP courses and exams, setting credit and placement policies, and scoring student work. The AP Higher Education section features information on recruitment and admission, advising and placement, and more.
This chart shows recommended scores for granting credit, and how much credit should be awarded, for each AP course. Your students can look up credit and placement policies for colleges and universities on the AP Credit Policy Search.
AP Course and Exam Development
The AP Program is unique in its reliance on development committees for their initial and ongoing voice in course and exam development. These committees, made up of an equal number of college faculty and experienced secondary AP teachers from across the country, are essential to the preparation of AP course curricula and exams.
