We develop a theoretical treatment of polarization spectroscopy and use it to make predictions about the general form of polarization spectra in the alkali-metal atoms. Using our model, we generate theoretical spectra for the $D2$ transitions in $^{87}\mathrm{Rb}$, $^{85}\mathrm{Rb}$, and $^{133}\mathrm{Cs}$. Experiments demonstrate that the model accurately reproduces spectra of transitions from the upper hyperfine level of the ground state only. Among these, the closed transition $F\ensuremath{\rightarrow}{F}^{\ensuremath{'}}=F+1$ dominates, with a steep gradient through line center ideally suited for use as a reference in laser locking.
