PLAINVILLE - Jackson School has earned continued accreditation from the New England Association of Schools and Colleges.

The association accepted the school's five-year progress report and commended the school specifically for implementing common planning time between and among grade levels, reinforcing differentiated instruction and strenghtening the use of portfolios and alternative assessments to inform curriculum decisions.

The association also acknowledged the school for expanding efforts to include parents and community members in its work, establishing a curriculum review calendar for the district, training teachers to assist English immersion students and developing and implementing a plan to expand the library.

The school is encouraged to continue work on developing common grade level assessments in math, science and social studies, finding opportunities for students to use portfolios for "self-reflection and self-assessment," and developing a K-6 health curriculum aligned to Massachusetts Health Curriculum guidelines.

Principal praised Superintendent David Raiche acknowledged Jackson School Principal Anne Houle for her role in the positive review.

"I think that's a testament to the work that goes on and the leadership that Anne brings to this school," Raiche said.

Jackson School is scheduled to host a visiting committee from the association for 10-year accreditation in the spring of 2013.
