Do insurance companies check to see if you have graduated high school?
No.
Nope...unless you're telling them you deserve a good student discount.
Not really, but if you don't have experience in the biz you are going to open and need commercial insurance, they usually ask for a resume.
If it's a contingency on your getting some kind of discount.
They can't
Are you asking as a client, or an employee?
They don't care if clients graduated or not.
For employees, they care - they most likely will do a backround check on you. If you have your GED, it's not a big deal that you didn't graduate from high school. If you don't, well, that becomes a big deal when they do the backround check, and find out you lied on the application. You won't get the job.
Answers:
As a client, no, unless you are the child of a policy holder and are getting a license for the first time, they will usually ask if you are in school and a good student, to give your parents a break. But if you are just getting a policy of your own, as a driver or renter, etc, for now it is one of the few industries that doesn't care if you are a graduate or not. As an employee, it is usually a requirement or equiv.
How would they? I can't recall ever putting something on an insurance application that would have given them the ability to check.
nope
