Chelmsford, Groton-Dunstable and Littleton were among 46 school districts across Massachusetts to be named to the 2012 AP Honor Roll, the state Department of Elementary and Secondary Education announced Tuesday.
Districts are judged based on how they've expanded access to advanced-placement curriculum, maintained access for minority students, and maintained or improved the rate of highest-performing exams.
Chelmsford, Groton-Dunstable and Littleton have all achieved the honor in multiple years, something done by only nine of the districts honored this year. This is the third annual list.
More districts from Massachusetts earned a spot on the national AP District Honor Roll than any other state, according to the education department.
"I congratulate these school districts for their efforts to expand access to, and success in, course work that signals readiness for a college-level curriculum," Mitchell Chester, the commissioner of elementary and secondary education, said in a statement.
"In Massachusetts, we are encouraging our schools to upgrade their program of study so that all students are ready for success beyond high school. The commonwealth's status of being the state with the most AP honor roll awardees is evidence of progress toward this goal."
