You can join your school's TPT School Express account by accepting an invitation from your school's administrator.
Once your administrator signs up for TPT School Express, they’ll invite you and other teachers to join the school account. You’ll receive an invitation email with a link to join. The email will be sent from info@teacherspayteachers.com.
