Summer school starts Tuesday, but fewer students will be attending than the Department of Education had expected.
The dip comes after a major Education Department policy change.
In April, Chancellor Carmen Fariña announced students would no longer be required to attend summer school based on test scores alone.
It's now up to principals to decide.
The department says 7.4 percent of elementary and middle school students were recommended for summer school this year—down from 10 percent in 2013.
When they announced the new policy, officials said they still expected schools would recommend about 10 percent of students.
Instead, summer school attendance will be at its lowest since 2010.
