Unfortunately, you cannot claim the Educator expenses deduction as you are not an eligible educator.
This is the IRS definition of an eligible educator:
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.
