While other speaking tests are judged by one person, TOEFL iBT’s speaking responses are scored by multiple trained raters. How does it work? It’s simple. Instead of an in-person interview with a rater from a local testing site, the TOEFL® test asks you to speak 6 times into a microphone. Your
responses are recorded, saved, and scored by several ETS raters. With other tests, interviewer’s mood can impact your score. If he or she has a bad day, you could earn a score you lower than you deserve.TOEFL’s multiple-rater grading system gives you more opportunities to get a fair evaluation and ensures that your score is reliable.
