The Pennsylvania Department of Education has released its annual list of Persistently Dangerous Schools.

While the School District of Philadelphia cut its number of dangerous schools by almost half in the last year, 10 high schools remain on the list. And four of them are in the Northeast.

Fels, Frankford, Lincoln and Northeast high schools all meet the state qualifications for the list, based on the variety and number of violent incidents among students during the school year. These four were on the 2011-2012 list, and all made the list in 2009-2010. Harding Middle School also made the 2009-10 list, but has since dropped off.
