Language Score is a free set of English tools to convert TOEIC, TOEFL, TEPS and OPIc scores, self-assess your English level, and take a vocabulary quiz.
All conversions and assessments run in your browser. We provide them transparently on the basis of CEFR, while clearly noting that results are reference estimates.
What is Language Score
Language Score is a free set of tools that helps students, professionals and job seekers preparing for English tests quickly gauge their current level and set goals. You can compare scores across different tests such as TOEIC, TOEFL, TEPS and OPIc through CEFR (Common European Framework of Reference), and check your skills with a quick self-assessment and a vocabulary quiz.
Operating Principles (E-E-A-T)
- Experience — The conversion flow is designed to answer the question learners ask most during real test prep: "What would my score be on another test?"
- Expertise — Conversions are based on each test's scale and CEFR mapping, such as TOEIC (L&R) out of 990, TOEFL iBT out of 120, and TEPS (2018 revised) out of 600.
- Authoritativeness — We link to official materials from the organizations that administer the tests, such as ETS and the TEPS committee.
- Trustworthiness — Every tool clearly states that conversion is an approximation, not an official 1:1 mapping, and your inputs are neither collected nor stored.
Data Sources
The conversion tables and CEFR mappings combine published materials and commonly used standards from the following organizations. Tests may be revised, and we update to the latest standards when they change.
- ETS TOEIC — TOEIC score and CEFR mapping
- ETS TOEFL — TOEFL iBT score and CEFR mapping
- TEPS Committee — TEPS (2018 revised) score and CEFR
- OPIc — OPIc grade system
A Note on Accuracy
All of Language Score's results are reference estimates based on published scales and CEFR mappings. Because each test measures different areas and scores differently, there is no official 1:1 conversion table between scores, and converted values are not accepted for official submissions such as admissions or jobs. The English level test and vocabulary quiz are also for self-checking and do not replace accredited scores. Please confirm accurate scores and acceptance criteria with each test's administering organization.
