Tickets aren't write-offs (deductible charitable donations). Write-offs come from financial contributions where the donor doesn't receive equivalent consideration. Usually, that means intangible (amorphous) benefits, such as "memberships", or accessories of minimal value, such as a school flag or a team calendar. Neither type of "benefit" is exclusive to educational institutions, and both are commonly used by charitable institutions to raise money. Raffles, parties, musical events, club memberships, accessories, etc. ... are also standard charitable fund-raising methods dating back to WWII. So it really doesn't matter if you 'get it' or not.
