What is AP Computer Science Principles?

Course Overview

AP Computer Science Principles (AP CSP) is an introductory college-level computing course designed to broaden participation in computer science. Unlike AP Computer Science A, which focuses primarily on Java programming, AP CSP takes a broader approach to computing, covering a wide range of fundamental topics.

The course emphasizes creative problem-solving, computational thinking, and real-world applications of computing. Students learn to analyze problems, work with data, and develop solutions that can impact their community and society.

Key Course Goals

  • Develop computational thinking skills
  • Create computational artifacts
  • Understand computing's global impact
  • Learn collaboration strategies
  • Practice responsible computing
