This report summarizes the flavor tagging techniques developed at the CDF and D0 experiments. Flavor tagging involves identification of the B meson flavor at production, whether its constituent is a quark or an anti-quark. It is crucial for measuring the oscillation frequency of neutral B mesons, both in the B{sup 0} and B{sub S} system. The two experiments have developed their unique approaches to flavor tagging, using neural networks, and likelihood methods to disentangle tracks from b decays from other tracks. This report discusses these techniques and the measurement of B{sup 0} mixing, as a means to calibrate the taggers.
