(NBC) - A majority of public school teachers spend their own money on classroom supplies without reimbursement.
According to a new survey by the Department of Education, teachers in 2014 through the 2015 school year spent an average of $479 out of their own pocket.
The supplies included pencils, chalk, construction paper as well as other supplies.
About seven percent spent more than $1,000.
The survey comes amid teacher protests in some states over salary.
