Background and Context. There is a constant, demonstrated need for valid and reliable assessments in computing education research. While there exist assessments at a course-based level (e.g., CS1, Data Structures, Discrete math, etc.), instructors and researchers would also like concept-based subscales that are more fine-grained. However, assessments designed and validated at the course level need additional work to determine whether they can reliably and validly measure individual concepts.
Objectives. In this paper, we explore the content and factor structure of an existing CS1 assessment, the Second CS1 (SCS1) assessment, which consists of nine CS1 concepts and three question types (definitional, …
