Students may sit for the TOFEL as many times as they wish to increase their score. A score is considered valid for two years from the test date. I recommend that students compare their TOEFL scores to that of the admissions requirements of schools that they are considering as good fit schools. If a student has a TOEFL score that is a good match with the schools that they are applying to then they should stop taking the exam. International students who attend a high school in the US and who are required to take the TOFEL to apply to an American college or university may apply for a fee waiver. The eligibility of a TOFEL fee waiver is determined by economic need and not by merit.
