Are verifications required if you have founded an organization?

I co-founded the music society of my high school along with seniors but didn’t receive any sort of formal verifications for the work. Will it be necessary or should I not list it in my Common App?

Could one of the teacher recommenders speak to your depth and breadth of your involvement in service to the school community and make sure to include this?

I don’t know what formal verification for the work would be, other than acknowledgement by faculty and administration, and maybe a mention on the school’s website listing the school’s clubs and activities. Probably not even there, actually, if you worked in tandem with others.

You can list it if it’s true.

No, you can list anything you want on the Common-App. No admissions officer is going to take the time to verify every applicant’s activities. Keep in mind that if you lie, you risk your admissions being rescinded! Go-ahead and list it; you don’t need any type of verification forms.

If a certain EC is what tips you into the accepted pile, they will likely attempt to verify. Something that would cause that tip should be easily verifiable through various media.
