In their general policy, school boards should include a periodic review of all pertinent facts regarding obsolescence, renovation, and rehabilitation of school buildings. Should the estimated cost of rehabilitation equal about 60 to 70 percent of the estimated cost of the replacement, in the long term assessment, it might be more satisfactory to build a new school. The available grant structure and debenture costs to the locality must be carefully investigated at the time the cost of the project is being estimated. A checklist should help indicate to school boards whether or not a school should be rehabilitated. Factors to be considered are educational obsolescence; and location, site, building structure, and services obsolescence. (Author/MLF)
