We present a psychometric evaluation of the Cybersecurity Curriculum Assessment (CCA), completed by 194 students from 7 colleges and universities. The CCA builds on our prior work developing and validating a Cybersecurity Concept Inventory (CCI), which measured students’ conceptual understanding of cybersecurity after a first course in the area. The CCA deepens the conceptual complexity and technical depth expectations, aiming to assess conceptual knowledge of students who had completed a multi-course curriculum in cybersecurity. We briefly present our development of the CCA before presenting our evaluation of the instrument using Classical Test Theory and Item-Response Theory. The CCA is a difficult assessment, providing reliable measurements of students’ knowledge and deeper information about high performing students.
