[2] You will apply for the examination with this office. After you have been determined eligible to sit for the examination, the Board will send an Authorization To Test (ATT) to NASBA. The ATT is valid for a period of 90 days. NASBA will send you an invoice for the test sections. The fees must be paid prior to expiration of the ATT. Once you have paid the appropriate fee, NASBA will send a Notice to Schedule (NTS). You will then call Prometric to schedule a testing appointment(s). The NTS will remain valid for a period of six months. That means you will have a set period of time from the date the NTS is issued to schedule and take the examination sections(s) for which you have applied. [0]
