FENTON — Armstrong-Ringsted, North Kossuth and Sentral school districts Wednesday night at Sentral School in Fenton narrowed down to two the number of consultants it is considering for a consolidation feasibility study. Educational Consulting Services (ECS) of Lincoln, Neb., and Ray & Associates, Inc., of Cedar Rapids were the consultants whose proposals the districts are considering. At a Tri-District meeting last month at Sentral, ECS representative Jerry McCall made a proposal which would cost an estimated $18,000 to $24,000 or $6,000 to $8,000 per district. In the Ray & Associates, Inc. proposal made by Dr. Robert Decker, the cost to the three districts would total $12,000, or $4,000 for each district. The boards Wednesday night also heard an on-line proposal by RSP & Associates, L.L.C. of Olathe, Kan. Robert Schwarz of RSP pegged a cost of $22,000 to $30,000 plus any architect or engineer’s fees.
