Major advances spanning several orders of magnitude in sensitivity are anticipated in the current round of experiments with rare kaon decays. Observations of allowed processes, like /Kappa//sup +/ /yields/ /pi//sup +/ /nu//nu/-bar and /Kappa//sup 0//sub L/ /yields/ /mu//sup +//mu//sup -/, shed light on detailed aspects of the standard model. New sources of T or CP violation could be manifested by measurements of muon polarization in /Kappa/ /yields/ /delta//mu//nu//sub /mu// and /Kappa//sup 0//sub L/ /yields/ /mu//sup +//mu//sup -/ decays and by studies of reactions like /Kappa//sup 0//sub L/ /yields/ /pi//sup 0/e/sup +/e/sup -/. Evidence for new particlews and new interactions could appear in advanced efforts to observe /Kappa/ /yields/ /pi/chichi' and /Kappa/ /yields/ /pi/chi decays, where chi and chi' represent hypothethetical neutral particles, and in searches for lepton flavor violating processes /Kappa//sup 0//sub L/ /yields/ /mu/e and /Kappa//sup +/ /yields/ /pi//sup +/ /mu/e. The experiments are reviewed and their theoretical context is discussed.
