In an embodiment, Applicant's method can automatically determine proficiency in a given language by tracking a user's gaze during reading a sample text. The language proficiency test includes reading sentences in a language (e.g., a language to the user's native language). The user's, or learner's, gaze is recorded using an eye-tracking camera while they read the sample text. Applicant's method and corresponding system predicts the language proficiency of the learner based on their gaze patterns. Applicant's method and corresponding system can also predict performance on specific standardized language proficiency tests such as Michigan EPT (Michigan English Proficiency Test), TOEIC® (Test of English for International Communication®), and TOEFL® (Test of English as a Foreign Language®).
