We calculate the chiral and thermal susceptibilities for two confining Dyson-Schwinger equation models of QCD with two light flavors, a quantitative analysis of which yields the critical exponents \ensuremathβ and \ensuremathδ that characterize the second-order chiral symmetry restoration transition. The method itself is of interest, minimizing the influence of numerical noise in the calculation of the order parameter for chiral symmetry breaking near the critical temperature. For the more realistic of the two models we estimate Tc\ensuremath≈153 MeV and the non-mean-field values \ensuremathβ=0.46\ifmmode±\else\textpm\fi0.04, \ensuremathδ=4.3\ifmmode±\else\textpm\fi0.3, and 1/(\ensuremathβ\ensuremathδ)=0.54\ifmmode±\else\textpm\fi0.05, which we discuss in comparison with the results of other models.
