How long are my GRE and TOEFL or IELTS scores valid?
Your GRE scores are good for five years from the testing date. TOEFL and IELTS are good for two years from the test date. Your TOEFL or IELTS need to be valid on the date that classes start for fall semester, which is usually the Tuesday after the first Monday in September. If they expire before that time, you will be required to retake the TOEFL or IELTS before you can enter the University.
