When will I receive my score reports?

That depends on the exam you've taken. How scores are reported, and when, is determined by the organization whose exam you've taken. In some cases, such as with many Information Technology exams, scores are available immediately following the exam and the test taker will know by the time he leaves the test center whether he passed. In other cases, the testing organization asks Prometric to send scores to them directly first, and then they send results to test takers. Please check with your exam sponsor for complete information.

How can I check the status of my certification? Why haven't I received it yet?

To obtain information about the status of your certification, you must contact the examination sponsor directly. Prometric delivers the exam on behalf of test sponsors, but the certification or license for which you are ultimately testing is managed by the organization whose exam you took.
