The final measurement of Re(ε'/ε) based on the full KTeV dataset is presented. The dataset contains about 15 million K-> π⁰ π⁰ and 70 million K-> π⁺ π^- decays allowing for significant improvement in precision compared to the previous KTeV result. The KTeV data are also used for new tests of the CPT symmetry. The value of Re(ε'/ε) is consistent with one obtained by the NA48 collaboration, the world average result provides a measurement of the direct CP violation with better than 10% precision.
