Psychometric Evaluation of the Cybersecurity Concept Inventory

Abstract

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.
