Here is a recent blog discussing the exam retake policy: https://blog.isc2.org/isc2_blog/2020/10/cissp-exam-retake-policy-change.html
Hello @Apple11
As mentioned in the CISSP Exam Retake Policy Change (https://blog.isc2.org/isc2_blog/2020/10/cissp-exam-retake-policy-change.html), if you don’t pass the exam on your third attempt (and for all subsequent retakes), you may retest after 90 test-free days from your most recent exam attempt. However you may only attempt a particular (ISC)² exam as many as four times during a 12-month period.
This exam retake policy change allows for more frequent re-testing, as well as consistency in policy between exams, which is a benefit to exam candidates.
If you have further questions regarding your specific situation and attempts at taking the exam, please reach out to our member and candidate support team at https://www.isc2.org/Contact-Us.
