Verdict: Hal Jordan went to school but didn't finish his degree.
This one took some thought. Hal is the first character in our "College Day" series not to have existed in the Golden Age, so that's an entire era of 'evidence' missing. Now, I could double-down by re-reading all of Hal Jordan's Silver Age stories for any trace mentions of his alum mater, BUT...
that would have involved me reading all Hal Jordan Silver Age stories, and, frankly, I'm not that dedicated and would rather be hit in the head repeatedly by a yellow lamp.
I simply know of NO mention during that period of Hal having gone to college; please inform me otherwise if you have such evidence. One of the problems with this is his job: he's a test pilot.
Now, in the Silver Age, it's believable that a private industry test pilot wouldn't necessarily have a Bachelor's. You don't need a college degree to fly a plane, even to fly it really well.
|It's disturbing who they'll let fly a plane.|
You still don't. I mean, it's LIKELY that a private test pilot would have a Bachelor's, because nowadays plenty of people do, so surely that would be the industry's preference. In fact, unlike in the Silver Age, you can now get a Masters in, well, being a Test Pilot.
To get a job with a college degree as a private test pilot with an airplane manufacturer, they'd have to, say, feel guilty for causing your dad's death, or you'd have to be sleeping with the owner's daughter or something.
But, in more recent times it's become Hal's backstory that he was in the USAF, where pilots get bachelor's degrees in the process of becoming pilots (since all pilots are officers). He joined the USAF against his mother's wishes at age 18 and then got kicked out for something stupid, like punching his CO in the face so he could go visit his dying mother.
|It became Hal's go-to solution.|
Which would mean that he was in test pilot school in the USAF, essentially getting a college degree as a test pilot, but didn't finish. So he would still have experience as a "USAF pilot".
Even though this backstory is a modern invention, it would explain a lot about Hal's life during the Bronze Age. Specifically the jobs he was taking when NOT test piloting. Toy salesman. Truck driver. Insurance adjuster. These are not occupations that demand a college degree (certainly not during the Bronze Age).
In any case, I'm not going to require of myself that I make sense of a backstory that actual creators may not have fully thought through. I simply can't reconcile whether Hal was or was not a USAF pilot BEFORE getting kicked out. If he was, he got his commission and a college degree.
|Even Grant Morrison, bringer of clarity, couldn't make sense of it!|
But if there is not evidence in any stories that Hal went to college and his job(s) don't actually require it and the ONLY thing that demands that he get a degree would be becoming an USAF pilot which he never actually go through doing then, I can pretty much come to no other conclusion than that Hal Jordan doesn't have a degree.
That said I'd love to be proven wrong, because I would very much enjoy making fun of whatever college gave Hal "Head Injury" Jordan a degree.
