Build Logic. Learn to Code. Compete with Confidence.

Is your child curious about computer science and ready to take their first big step into competitive programming?
The Masterpiece Academy ACSL Junior Division Team gives students in Grades 4–9 the chance to explore the core foundations of computer science while preparing for the American Computer Science League (ACSL) Junior Division contests.

Students learn to think logically, solve problems creatively, and gain hands-on experience in Python programming, while building confidence through structured lessons, weekly practice, and real ACSL-style contests.

About the ACSL Junior Division

The ACSL Junior Division introduces students to the fundamental building blocks of computer science through two key components:

  1. Short Problems – covering essential theory and logic topics such as:

    • Number Systems

    • Prefix / Infix / Postfix Notation

    • Boolean Algebra

    • Graph Theory

    • Recursive Functions, Data Structures, and more

  2. Programming Problems – hands-on coding challenges using Python, Java, or C++ (our program teaches Python for clarity and accessibility).

Our curriculum combines structured instruction, guided practice, and competitive preparation to help students maximize scores in every ACSL contest round.

What’s Included

  • ACSL Elementary Textbook and printed learning materials

  • Number Systems Practice Book for extra drills

  • Weekly in-person classes (each recorded for review access)

  • Weekly homework assignments to reinforce concepts

  • At least two full practice tests per contest

  • Introduction to Python from an ACSL problem-solving perspective

  • Google Group access for parent–student communication

  • Official Certificate of Participation upon completion

Our combination of expert teaching, structured materials, and ongoing feedback makes it easy for both students and parents to follow progress and stay motivated.
