A　proposal　is　made　for　testing　symmetrization　postulate　(SP)　for　photons　in　the　context　of　cavity　QED.　In　the　scheme　sequences　of　two　Λ-type　three-level　atoms　are　sent　through　a　cavity　filled　with　a　coherent　field.　After　Raman-type　interactions,　the　atoms　are　state-selective　measured.　The　two　atoms　would　be　detected　in　the　same　state　when　the　SP　holds.　The　probability　that　the　two　atoms　are　found　in　different　states　characterizes　the　violation　of　the　SP.
