Exploratory factor analysis (EFA) is one of the standard analytical techniques used in EFL studies. It helps researchers to identify hidden constructs and check whether the survey instruments capture learners' beliefs, feelings and attitudes in EFL classrooms. However, many struggle with the application of EFA due to a lack of clear rationale for each step and practical advice on how to conduct the analysis. This article therefore provides a comprehensive guide to EFA, focusing specifically on the EFL context. To make implementation systematic, the 7Rs steps--Reflecting, Recruiting, Reviewing, Reducing, Retaining, Rotating and Renaming--are presented as a step-by-step guide to performing the technique. Using these steps, researchers will be able to perform EFA in a way that is consistent with the theory being tested while meeting basic statistical standards. Readers are thus provided with practical tools for creating questionnaires that are not only valid and reliable but can also be used in EFL contexts.
