Each fall, ISM publishes a set of conversion factors to facilitate recasting previous tuitions into current dollars. (See the accompanying table.) We continue to use the Urban Consumer Price Index (CPI-U).1 However, we also realize the CPI-U does not completely reflect expenditures in private-independent schools; it can only serve as a base figure. There are compelling arguments for adjusting your tuition at a rate 2% above the overall inflation rate.2 The CPI has a built-in “productivity factor.” It assumes the workforce is increasingly productive as computers, streamlined mechanical devices, and other laborsaving developments provide greater output with fewer personnel. The more efficient a business becomes, the more the business can stabilize or reduce the effects of inflation.
