Boards of accountancy will set a time period for which an NTS is valid （generally six months） during which you must schedule and take the examination section（s）， after which it will expire and all fees will be forfeited. It is strongly suggested that you not apply for a section of the examination until you are ready to take it. If you do not take all sections for which you registered before the NTS expires， you will not be able to extend it or receive a refund of any of the fees you have paid. Please be advised that cancelling an Exam appointment does NOT change the expiration date of your NTS. All jurisdictions have established a six-month NTS validation period， except for the following jurisdictions：
　　Texas 90 days from application date
　　California 9 months from NTS issue date
　　Hawaii 9 months from NTS issue date
　　Louisiana 9 months from NTS issue date
　　Utah 9 months from NTS issue date
　　North Dakota 12 months from NTS issue date
　　South Dakota 12 months from NTS issue date
　　Virginia 12 months from NTS issue date
