NEW YORK - A new report is shining a light on a lack of arts teachers in New York City public schools. 

According to City Comptroller Scott Stringer, 20 percent of public schools lack any arts teachers, including one out of seven middle and high schools. 

The report, which is based on data from the Department of Education, also says that more than 42 percent of those schools are concentrated in the South Bronx and central Brooklyn. 

State law requires that all middle and high school students receive arts instruction.
