1973 — A complete tax base
equalization program is enacted that provides a much higher appropriation of
equalization aid to relieve local property taxes; discontinues general flat
aids; institutes a power equalizing program providing for «negative
aids»; and separates the shared cost into
primary and secondary levels with a two - level system of state
aid in which school costs which exceed the statutory ceiling of aidable costs are supported at a lower level of state
aid to serve as a disincentive to high levels of spending.
