Journal ArticlePsychometric Evaluation of the Cybersecurity Concept InventoryPoulsen, Seth; Herman, Geoffrey L.; Peterson, Peter A.; Golaszewski, Enis; Gorti, Akshita; Oliva, Linda; Scheponik, Travis; Sherman, Alan T.We present a psychometric evaluation of a revised version of the Cybersecurity Concept Inventory (CCI) , completed by 354 students from 29 colleges and universities. The CCI is a conceptual test of understanding created to enable research on instruction quality in cybersecurity education. This work extends previous expert review and small-scale pilot testing of the CCI. Results show that the CCI aligns with a curriculum many instructors expect from an introductory cybersecurity course, and that it is a valid and reliable tool for assessing what conceptual cybersecurity knowledge students learned.2022-03-3110313692ACM Transactions on Computing Education2211946-6226https://doi.org/10.1145/34513461820531National Science Foundation
