CSLA estimates the CEFR-J level of English learners' spoken production based on transcribed text (A1.1, A1.2, A1.3, A2.1, A2.2, B1.1, B1.2, B2.1, B2.2, C). Please input 10–500 words of text. The tool is primarily designed for high school–level learner data and is part of the same family of tools as CVLA (reading) and CWLA (writing).
