AP Computer Science Principles Exam: An Overview

The AP Computer Science Principles (AP CSP) Exam evaluates students’ understanding of computational thinking practices and the core concepts taught throughout the course. It is designed to assess both conceptual knowledge and practical programming skills.

The exam consists of two main components:

The Create Performance Task
The End-of-Course AP Exam

In this section, we will break down the structure, scoring, preparation strategies, and key tips for exam success.

Structure and Format of the AP CSP Exam

The AP Computer Science Principles Exam is a 2-hour assessment that measures students’ understanding of computing concepts, problem-solving skills, and programming abilities.

1. Multiple-Choice Section (70% of total score)

This section tests conceptual understanding and includes three question types:

Single-select multiple-choice questions
- Students choose one correct answer from several options.
- There are 57 questions in this format.
Single-select questions with reading passages
- Each question is based on a short passage about technology or computing innovations.
- Students analyze the passage before selecting the correct answer.
- There are 5 questions in this format.
Multi-select multiple-choice questions
- Students select more than one correct answer.
- There are 8 questions in this format.

2. Create Performance Task (30% of total score)

The Create Performance Task is a hands-on component of AP Computer Science Principles where students demonstrate their ability to design and build a program.

Students are required to:

Develop a computer program that solves a problem, expresses creativity, or explores a personal interest
Submit the final program code
Record and submit a video showing the program in action
Provide written responses explaining their design choices and development process

This task requires at least 12 hours of dedicated class time and emphasizes creativity, problem-solving, and real-world application of computing concepts.

Understanding the Exam Rubrics and Scoring Guidelines in AP Computer Science Principles

To do well on the AP Computer Science Principles exam, it’s essential to understand how your work is evaluated. The College Board releases scoring guidelines each year, including the passing score threshold and detailed rubrics that explain exactly how student responses are graded.

For the 2026 AP Computer Science Principles scoring guidelines, each part of the Create Performance Task is broken down into specific criteria. These criteria show what examiners are looking for when they assess your program, written responses, and supporting evidence.

Below is a clear breakdown of each scoring row in the Create Performance Task rubric:

Row 1: Program Purpose and Function

In this section, you must show your program running through a video that clearly demonstrates input, functionality, and output. Your written response should explain what the program is designed to do, how it works in practice, and how the input leads to specific outputs shown in the video. Screenshots or storyboards are not accepted. The purpose of the program should clearly connect to either a real-world problem or a creative idea you are exploring in AP Computer Science Principles.

Row 2: Data Abstraction

Here, your written response must include two distinct code segments. One should show how data is stored in a list or collection, while the other should demonstrate how that stored data is used within the program. You also need to identify the variable that represents the list and explain why that data is meaningful. Simply trivially using a list or including only one element will not earn credit.

Row 3: Managing Complexity

In this section, you explain how using a list helps simplify or improve your program. You must include a code segment showing the list in use and describe why the program would be more complicated or different without it. Even if you did not earn a point in Row 2, you can still earn credit here. However, the explanation must be realistic, and the list must play a meaningful role in reducing complexity within your AP Computer Science Principles project.

Row 4: Procedural Abstraction

This part requires two code segments: one showing a student-developed procedure with at least one parameter, and another showing where that procedure is called. You must also explain the purpose of the procedure and how it contributes to the overall program. Procedures without parameters or unclear explanations will not earn points in this section.

Row 5: Algorithm Implementation

You must include a student-developed algorithm that clearly demonstrates sequencing, selection, and iteration. Your explanation should walk through how the algorithm works step by step so someone else could recreate it. Simply describing what the algorithm does without explaining how it works, or failing to include the code, will result in no credit.

Row 6: Testing

In this final section, you must describe two different calls to your procedure using different arguments. These calls should produce different outcomes or execute different parts of your code. You also need to explain the conditions being tested and the results produced. To earn points, your test cases must be clearly different and correctly connected to your procedure within your AP Computer Science Principles submission.
