PAs can take the PANRE a maximum of four times (two times in their 9th year and up to three times in their 10th year of the certification maintenance process). You can only take the PANRE once in a 90-day period. However, this 90-day rule is waived for one final attempt if there are fewer than 90 days remaining in your 10th year and you have not used all four of your examination attempts.
