About this resource

This quiz focuses on programming fundamentals within the context of AP Computer Science Principles, specifically targeting conditional statements, functions, and program flow control. Designed for high school students in grades 9-12, the assessment evaluates students' ability to trace through code execution, predict program outputs, and understand control structures like if-else statements and loops. Students must demonstrate mastery of core programming concepts including variable manipulation, Boolean expressions, function declaration and calling, and debugging skills. The questions require computational thinking skills as students analyze code snippets, identify logical errors, and determine correct syntax for conditional logic. Success on this quiz demands understanding of how programs execute sequentially, how conditions affect program flow, and how functions can eliminate code redundancy while improving program organization. Created by Jennifer O'Keefe, a Computer Science teacher in the US who teaches grades 9-12. This assessment serves as an excellent formative evaluation tool for Unit 4 of the AP Computer Science Principles curriculum, allowing teachers to gauge student comprehension before advancing to more complex programming concepts. The quiz works effectively as a review activity following instruction on conditionals and functions, or as homework to reinforce classroom learning about program control structures. Teachers can use this as a warm-up activity to activate prior knowledge before introducing nested conditionals or more advanced function concepts. The varied question formats—from code tracing to debugging scenarios—provide comprehensive insight into student understanding and help identify specific areas where additional instruction may be needed. This assessment aligns with AP CSP Learning Objectives related to algorithms and programming, particularly those addressing conditional statements (AAP-2.H) and the use of procedures and functions (AAP-3.A, AAP-3.B).
