MANCHESTER — Regional School Unit 38 officials agreed Wednesday night to conduct additional air quality testing of classrooms at Manchester Elementary School in response to parents’ concerns over how the district and school administration handled a mold problem late last year. School board Chairwoman Terri Watson said additional classrooms would be tested Thursday, and she assured parents that test results would be available immediately after the district receives the report. “If we are informed that there is a potential danger to students, we will notify parents and we will work to relocate students if necessary,” Watson said. Jenny Kingsbury, president of the school’s Parent, Teacher, Community Organization, made several requests of the district and school administration aimed at ensuring better communication with parents. The organization requested the creation of an oversight committee including parents, teachers and staff; and for air, surface and carpet testing in the entire school.
