High precision measurements of the parity-violating asymmetry in polarizedelectron scattering from nuclei can be used to extract information on nuclearand nucleon structure or to determine Standard Model couplings and higher-orderradiative corrections. To this end, low uncertainties are also required in theeffects that inevitably arise from modeling the underlying nuclear structure.An experimental precision of a few tenths of a percent may be attainable forthe asymmetry if the appropriate kinematic range is chosen, as will bediscussed here for the case of $^{12}$C. And given this, the dual goal ofascertaining both the sizes of various nuclear structure related effects and ofproviding estimates of their uncertainties for this particular target will bediscussed.
