Define the terms: letter of eligibility & ATT

2. After the board of nursing declares a candidate eligible, they will receive an Authorization to Test (ATT). If a candidate chooses to provide an e-mail address, all correspondence from Pearson VUE will arrive ONLY by e-mail. If a candidate does not provide an e-mail address all correspondence will arrive ONLY through U.S. mail. A candidate must have their ATT to schedule an appointment to take the NCLEX examination and they must present their ATT at the test center on the day of their examination to be admitted to the examination. Candidates will not be admitted to the examination without their ATT's and will be required to re-register and re-pay to take the examination.

The CA Boards send the applicant the eligibility letter that they are eligible to test and how to contact Pearson Vue to register. After the applicant sends the 200 to Pearson Vue, Pearson Vue sends a confirmation and you should recieve your ATT a few days after the confirmation (if you put an email, 1-5 days, if you do not give Pearson Vue an email, regular mail 5-10 days). The ATT gives you the information on scheduling your test location/date. As the previous person indicated, you must take that ATT to the exam with you and your name should match with your picture ID (see info from Pearson on name change documents they will accept at the testing site) otherwise they will turn you away and you'll have to pay both the Board of Nursing and Pearson Vue again. If Jr or SR is on your picture ID, put it on your application to the Board and when registering with Pearson Vue.
