Abstract Despite their small occupancy, the apical oxygen {ital p}{sub {ital z}} states have the indirect effect of modifying the relative occupancy of holes in states with different local symmetries in the CuO{sub 2} planes. A well-defined correlation is found between the maximum critical temperature {ital T}{sub {ital c}}{sup max} of various cuprates and the excess of holes in states with local {ital a}{sub 1} symmetry with respect to the doping {delta}{sup max} at which {ital T}{sub {ital c}}{sup max} is obtained for each compound. Implications for superconductivity models are discussed.
