How does my health insurance company know im in school?

Other than when i sent my class schedule, how does my health insurance carrier verify that im taking classes?

The application form under any insurance policy is very important and is considered a part of the policy. Insurance is based on the principle of good faith. The insurance company assumes a risk based on the application form on good faith which the assumption that whatever you have stated is true. Now when you place a claim with the insurance company, they will verify that whatever you have declared at the time of insurance is true. If they do not get a proof of your being in school at the time of the claim - than they can deny your claim on grounds of misrepresentation. Thanks.
