In this work we define a test to compare several square contingency tables under the quasi-symmetry model. Working within the class of log-linear models, we present a suitable model and an exact test to verify if two or more tables fit a common quasi-symmetry model. The exact test is then defined through classical tools of Algebraic Statistics, namely the computation of a Markov basis and the application of a MCMC algorithm.
