Can people from SD assume the License Look up is accurate? Or is it best to wait for actual results before stating we passed?
I personally would treat it as 100% accurate - especially since it's SD.
Technically the license lookup is the official word, not NCEES. If you are found there as a licensed PE, then you ARE a licensed PE!
With that said, we have seen a few cases over the years where it happens in error. In Oct 2014, Pennsylvania was a mess. Maybe 10% got their results early and accidently. PA closed that loophole. Then they accidently licensed people who failed. Someone (either PA staff or PCS) started issuing licenses to everyone who took the exam that October. A few people who failed, could find themselves in the license lookup. We estimate a many dozens of people were accidently issued a license. PA never notified people that they were issued a license though. PA caught the mistake after a day or so and started making the corrections. That mistake, and others that cycle, added nearly a month to the official release date.
We also heard of one person in Nebraska a few years ago, FNG staff person accidently issued a license to him and sent notification before the NCEES release. Then he found out he failed. Nebraska rescinded his license.
Now, SD ha so few people who take the test, and fewer that pass. So they enter the passes into the system first, takes a couple hours to enter everyone in. Then mail out envelopes to people who pass. Then allow NCEES to release the results. With such as small number, I'm inclined to believe that they won't have many false positives.
tl;dr. You passed. Your team is up by 5 pts. You have the ball, 2nd down, 8 seconds left on the clock, opponent has no timeouts. All your team has to do is take a victory knee. It's nearly a lock that your team will win.
