Uncertainty remains about redistricting and other recommendations identified in a recent efficiency study of the Amherst Public Schools. The report release in August, was among the items up for debate by the school board during a daylong work retreat held this week. Initially, the discussion was table; and the topic removed from the agenda at a Board of Supervisor’s meeting held earlier this month until some questions are addressed, such as the division’s enrollment projections; and cost analysis. Some decisions will need to be made on the most pressing issues, before recommendations are brought back before the Board of Supervisors.
