GMAT scores are valid for five years, with one retest permitted. The scores are available for reporting for up to 10 years. You can use score reports from GMAT taken 5-10 years ago by paying a fee. These scores are sent directly to the school with the caveat that they should be interpreted with caution. Many schools do not accept previous GMAT scores, so you should check with the school before placing a request for an old score report. You can order a score report older than 5 years by contacting the GMAT Customer Service provider in your region.
