If you work at the district-level for multiple schools (central office instructional coach), can you still claim the educator expense deduction for supplies?

I am based in the field and support multiple schools. Can I claim this deduction for education supplies I purchase and deliver to schools?

It does not need to be the same school. 

According to the IRS:

"You're an eligible educator if, for the tax year you're a kindergarten through grade 12 teacher, instructor, counselor, principal or aide for at least 900 hours a school year in a school that provides elementary or secondary education as determined under state law."
