Important Updates
New Curricula Available
We’re excited to announce that College Board has endorsed additional AP Computer Science A (CSA) ready-to-use curricula that come with preapproved syllabi, lesson plans, and other instructional supports, delivered by endorsed providers. See the list of offerings.
AP Computer Science Female Diversity Award Winners
1,119 schools are being recognized for their work toward equal gender representation during the 2019-20 school year, nearly 37% more than the 818 schools recognized last year. Find out more.
New AP Course Pacing Guide
This pacing guide (.pdf/199.97 KB), designed for classrooms that have only completed approximately 25% of typical course content by January, can help students develop their knowledge and skills by May. If your students are ahead of this pace, you’ll be able to incorporate additional days or weeks to spend more time on challenging topics, practice course skills, or begin reviewing for the exam.
AP Daily and AP Classroom
Short, searchable AP Daily videos can be assigned alongside topic questions to help you cover all course content, skills, and task models, and check student understanding. Unlock personal progress checks so students can demonstrate their knowledge and skills unit by unit and use the progress dashboard to highlight progress and additional areas for support. As the exam approaches, assign AP practice exams in the AP Classroom question bank and encourage students to take advantage of AP Daily: Live Review sessions April 19–29.
College Board–Endorsed Curricula Available
AP Computer Science A teachers can now adopt innovative curricula delivered by educational organizations. All these curricula are endorsed by College Board, are aligned to the updated course and exam description, and come with syllabi, lesson plans, and other instructional supports for teachers. Teachers who adopt one of these curricula can still use all the instructional resources that are accessible on AP Classroom.
Course Overview
AP Computer Science A is an introductory college-level computer science course. Students cultivate their understanding of coding through analyzing, writing, and testing code as they explore concepts like modularity, variables, and control structures.

AP Computer Science A CED Errata Sheet
This document details the updates made to the course and exam description (CED) in September 2019. It includes printable copies of the updated pages, which can be used as replacement sheets in your CED binder. Note: It does not include the scoring guidelines, which were added to the online CED in the summer of 2020.

AP Computer Science A CED Scoring Guidelines
This document details how each of the sample free-response questions in the course and exam description (CED) would be scored. This information is now in the online CED but was not included in the binders teachers received in 2019.
Course Content
Based on the Understanding by Design® (Wiggins and McTighe) model, this course framework provides a description of the course requirements necessary for student success, with a focus on big ideas that encompass core principles, theories, and processes of the discipline. The framework also encourages instruction that prepares students for advanced computer science coursework and its integration into a wide array of STEM-related fields.
The AP Computer Science A framework is organized into 10 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.
