    AP Computer Science Principles Exam Day 2019

    • Noon | 2 hrs

Assessment Overview

The AP Computer Science Principles Assessment consists of two parts: performance tasks and the end-of-course AP Exam. Both measure student achievement of the course learning objectives.

Assessment Format

Two Performance Tasks | 40% of Overall AP Score

  • Create — Applications from Ideas | 24% | 12 hours
  • Explore — Impact of Computing Innovations | 16% | 8 hours

The Create performance task focuses specifically on the creation of a computer program through the collaborative and iterative process of programming.

The Explore performance task requires students to identify a computing innovation, explore its impact, and create a related digital artifact – ex. digital art, video – accompanied by a written response.

We have pulled the Reproducible for Students section from the Course and Exam Description to create a new publication titled Assessment Overview and Performance Task Directions for Students. Please download and share this document with your students, as it provides instructions around the performance tasks and explanations on questions they will see on the AP Exam.

End-of-Course Exam: 74 Questions | 2 Hours | 60% of Overall AP Score

  • Single-select and multiple-select questions

The AP Computer Science Principles Course and Exam Description (.pdf/2.05MB) includes complete information about the performance tasks and the end-of-course exam.


Scoring Guidelines and Notes for the 2019 Exam Administration

We have provided clearer instructions in the decision rules and scoring notes column for the AP CSP Create and Explore Performance Tasks. Note that the intent of these updates is to clarify how the rubric should be applied to prepare for the 2019 exam administration. Our changes do not affect the number of rubric rows or the scoring criteria of the rubrics. See what changed.
