We present the matrix elements for the semileptonic kaon decays Kl2γ, Kl2l+l-, Kl2l'+l'-, Kl3, Kl3γ and Kl4 at next-to-leading order in chiral perturbation theory and compare the predictions with experimental data. Monte Carlo event generators are used to calculate the corresponding rates at DAFNE. We discuss the possibilities to improve our knowledge of the low-energy structure of the Standard Model at this and similar machines.
