This paper introduced change-point detection into the study of language educational measurement.Taking the development of language learners＇ writing ability as an example,it demonstrated every step of how to apply the software called change-point analyzer（ CPA in abbr.） to the detection of language ability development. It is hoped that more researchers interested in change point detection and analysis would get to know the operation of CPA so as to broaden the scope of studies in the humanities,integrate interdisciplinary studies,and eventually promote the disciplinary development as well as the methodological innovation.
