I work at an educational facility that isn't a school in South Kore, can I get a teacher's discount?

I'd check with your school first to see if they have an institutional subscription.

If they don't, you can contact Adobe on this page to see if you qualify and, if you do, how to prove it to them.

Hi,

Thank you for posting your query here. 

Since this is a User forum, I am not confident if you will get a correct response regarding if you qualify for the discount or not. You may refer to a similar thread :  https://community.adobe.com/t5/download-install/student-teacher-discount-uk/td-p/9549949 

Hope it helps.

Thank you.
