We extend a recent perturbative framework in standard model to the schemes with sterile neutrinos. In vacuum the framework will give strictly accurate oscillation probabilities. Moreover, it can remove degeneracies of the zeroth order eigenvalues so the perturbative expressions are valid for most baselines and neutrino energies. Numerical tests show that the perturbatively calculated...
