See the Updated Course Framework

To give teachers more clarity about course content and help students engage with the concepts, we’ve made minor updates to the AP Chemistry course framework.

These updates take effect with the 2024-25 school year. The scope of the course is not changing.

What’s Changing 

We made minor updates to the AP Chemistry framework in the updated course and exam description (CED), including:  

  • Retitling 4 units and 6 topics to more accurately describe the content, based on feedback we’ve received from AP Chemistry teachers.  
  • Resequencing Topics 7.13 (pH and Solubility) and 7.14 (Free Energy of Dissolution) to help students better engage with the concepts. 
  • Updating the equation sheet to better organize the information and for consistency with other AP science courses.  
  • Removing big ideas and enduring understandings from the framework. 
  • Updating learning objectives (LOs), essential knowledge (EK) statements, and skills to align with the resequenced topics and for greater transparency. 

What’s Not Changing 

  • The scope of the AP Chemistry course is not changing. 
  • The sections, numbers and types of questions, timing, and percentages of units and skills assessed on the AP Chemistry Exam remain the same.

Why did you make these updates?

We updated the course framework to provide a more complete and accurate description of the essential knowledge students must demonstrate on the AP Chemistry Exam and to address concerns around the topic sequencing and unit structure within the course.

Who was involved in updating the course?

As with all AP courses, a development committee including experienced educators and college faculty made the AP Chemistry updates. The AP Chemistry Development Committee also worked with high school teachers and higher education faculty reviewers and consultants.
