The Massachusetts Teachers Union and local NAACP are teaming to tackle a gap in education achievement they say affects students of color and low-income students.

The partnership's priorities will include recruiting more minorities as public school teachers, improving early childhood education for the target group of students, and keeping highly qualified teachers at hard-to-staff urban schools.

As of one its goals, officials say the partnership will promote disciplinary measures that don't take students out of the classroom following nonviolent offenses.
