On the basis of previous measuring tools, we took the Delphi expert consultation method to design the 5-level Likert Scale for Chinese EFL Learners’ English Thinking Ability. Nearly 600 EFL learners were tested, and the data were statistically analyzed by exploratory and confirmatory factor analysis. The results show that: 1) The Cronbach’s α general coefficient reaches above 0.9 and the correlation of each factor is significant; 2) The first-order structural model of three-factor English thinking ability has a good fit and so does the second-order model. The convergent and discriminant validity are good, with AVE values ranging from 0.430 to 0.527, CR>0.8. It can be concluded that the scale can reflect Chinese EFL learners’ grasp of English linguistic features and English cultural traits, and can be used as a tool to test English thinking ability.
