We review models for spin-weighted parton distributions in a proton. Sum rules involving the nonsinglet components of the structure function xg{sub 1}{sup p} help narrow the range of parameters in these models. The contribution of the {gamma}{sub 5} anomaly term depends on the size of the integrated polarized gluon distribution and experimental predictions depend on its size. We have proposed three models for the polarized gluon distributions, whose range is considerable. These model distributions give an overall range is considerable. These model distributions give an overall range of parameters that can be tested with polarized beam experiments. These are discussed with regard to specific predictions for polarized beam experiments at energies typical of UNK.
