- Written Responses (4 points): You must provide written responses explaining your program's purpose, functionality, and development process. This includes describing the algorithm used, explaining how abstraction manages complexity, and discussing the program's development process.
Scoring: Points are awarded for correct implementation of algorithms and abstractions, functional program execution, and clear, detailed written explanations. The Create Performance Task is submitted digitally before the exam date and is scored by College Board readers.
What is the Create Performance Task?
The Create Performance Task is a long-term project that you complete during the course. Unlike traditional exam questions, this task allows you to demonstrate your programming skills and computational thinking through a project of your choice. You must create a program that solves a problem or expresses creativity, document your process, and submit both your program code and written responses.
Key Requirements for the Create Performance Task
|
Algorithm Implementation
Your program must include at least one algorithm that integrates mathematical and/or logical concepts. The algorithm must be implemented in code and contribute to the program's purpose. |
|
|
Abstraction
Your program must use at least one abstraction (such as a function, procedure, or class) to manage complexity. The abstraction must be implemented in code and help organize your program. |
|
|
Data Storage
Your program must use data stored in a list or other collection type. This demonstrates your ability to work with data structures. |

Written Documentation
You must provide written responses explaining your program's purpose, functionality, algorithm, abstraction, and development process. Clear documentation is essential for earning full points. |
Scoring Process and Weightings
The AP Computer Science Principles exam uses a weighted scoring system to ensure both components contribute equally to your final score.
Raw Score Calculation
Your raw scores are calculated as follows:
- MCQ Raw Score: Number of correct answers (0-70 points)
- Create Performance Task Raw Score: Points from the Create Performance Task (0-6 points: Program Code 1 pt, Program Functionality 1 pt, Written Responses 4 pts)
Score Weightings (2025 Guidelines)
According to the latest College Board guidelines, both components are weighted equally:
- MCQ Section: 50% of total score (70 questions)
- Create Performance Task: 50% of total score (6 points total: Program Code 1 pt, Program Functionality 1 pt, Written Responses 4 pts)
This equal weighting means that performing well on both components is essential. Since the Create Performance Task is worth fewer total points (6) compared to MCQ questions (70), each Create Performance Task point has significantly more impact on your final score than each MCQ point.
Composite Score Calculation
Your raw scores from both components are combined into a composite score using the following process:
Scaling Process
The College Board scales your raw scores to ensure equal weighting:
- MCQ Scaled Score: Your MCQ raw score (0-70) is scaled to 50 points
- Create Performance Task Scaled Score: Your Create Performance Task raw score (0-6) is scaled to 50 points
- Total Composite Score: Sum of scaled scores = 0-100 points
For example, if you score 56 out of 70 on MCQ and 5 out of 6 on Create Performance Task:
- MCQ scaled: (56/70) × 50 = 40.0 points
- Create Performance Task scaled: (5/6) × 50 = 41.7 points
- Composite score: 40.0 + 41.7 = 81.7 points (rounded to 82)
AP Score Conversion (1-5 Scale)
Your composite score (0-100) is converted to the final AP score of 1-5 using a statistical process called equating. This process accounts for exam difficulty and ensures scores are comparable across different exam administrations.
