Abstract

Statistical process control (SPC) charts have been widely used in the field of educational measurement. The cumulative sum (CUSUM) is an established SPC method to detect aberrant responses for educational assessments. There are many studies that investigated the performance of CUSUM in different test settings. This paper describes the CUSUM procedure and shows how it can be used to monitor the test-taking process and detect aberrant responses. It aims to provide an accessible guide for the CUSUM control chart.

Keywords: CUSUM, Aberrant response, PFS
