CommonLit might list your school under a different zip code than you initially entered. Do a quick check for your school using other zip codes in your community.
To figure out which zip code your school would be under, you can go to https://nces.ed.gov/ccd/schoolsearch/ (for public schools) or https://nces.ed.gov/surveys/pss/privateschoolsearch/ (for private schools.)
If you still cannot find your school, sign up for "Other (USA)" and type in your school name.
We're unlikely to have newly created schools in the system. You can email us at email@example.com about adding your school to our system!
