It is the most common question that is registered among the OET aspirants, and understandably so. Well, there is no specific time frame or validity period determined by the OET authority, and hence there is no validity period as far as the OET administration is concerned. However, your organization/institution in which you are seeking admission or employment decides the validity period of the scores you got in the OET, which is mostly two years from the date of the announcement of result. Hence, it would be best to keep a tab on the minimum scores and validity period of the OET scores that your preferred organization has decided.
