Future AP Computer Science A Revisions
We’re revising AP Computer Science A to align with current introductory college programming courses. The earliest these revisions will launch is the 2025-26 school year.
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.

Course and Exam Description
Course Resources
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.

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.
Meet the AP Computer Science A Development Committee
The AP Program is unique in its reliance on Development Committees. 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.
