You should be eligible to sit for the exam under the category E3 Lapsed Nurse Aide or E4 Lapsed Out-of-State Nurse Aide (see the link to the exam registration form below). An E-3 or E-4 candidate has only one opportunity to successfully pass the NNAAP Examination. If the examination is failed, you must complete nurse aide training again and reapply for the exam.
