NEASC Self-Study Report

Mark T. Sheehan High School is accredited by the New England Association of Schools and Colleges (NEASC). This accreditation assures that tax money is supporting a school facility and programs that have been judged worthwhile by an outside team of evaluators, both in terms of the school’s stated mission and expectations and in terms of the school’s adherence to the Association’s Standards for Accreditation. The Standards address curriculum, instruction, assessment, school culture, school resources, and community resources.

Students are most affected by accreditation since they are the central focus of the educational process. Accreditation assures them that their needs are being met through a quality educational program, that a vehicle exists to correct deficiencies that may be present in the school program, that their transfer credits will more likely be accepted should their family move, and that college representatives have the assurance of the quality of their preparation.

Continued accreditation is dependent upon a school demonstrating ongoing, reflective progress to improve teaching and learning and the support of teaching and learning. To that end, the Sheehan faculty embarked upon and recently completed an extensive two-year self-study. To support them in this work, feedback was sought from various constituents including parents, students, and Board of Education members through the online version of the Endicott Opinion Survey.

NEASC Self-Study Report for Accreditation Visit, November 15 - 18, 2015

NEASC Report of the Visiting Committee

Mark T. Sheehan High School is accredited by the New England Association of Schools and Colleges, Inc. (NEASC), a nationally recognized organization. Accreditation is an ongoing process which requires schools to meet the Standards for Accreditation that reflect best practices for teaching and learning and to demonstrate school improvement monitored through peer review. The accreditation program involves a threefold process:a self-study conducted by the school’s staff, an on-site evaluation conducted by a NEASC visiting committee, and a follow-up program carried out by the school to implement the findings of the self-study and valid recommendations of the visiting committee.

The Sheehan self-study took place from August 2013 to June 2015. Students and parents joined the professional staff in the self-study deliberations. Following the completion of the self-study, a group of sixteen educators appointed by NEASC visited the school from November 15 through November 18, 2015. During this time, they met with students, parents, school and district personnel, observed classes, and reviewed the self-study documents to determine the degree to which the school meets the NEASC Standards for Accreditation. Based on their findings, Mark T. Sheehan was awarded continued accreditation in the New England Association of Schools and Colleges.
