Stellar evolution computations provide the foundation of several methodsapplied to study the evolutionary properties of stars and stellar populations,both Galactic and extragalactic. The accuracy of the results obtained withthese techniques is linked to the accuracy of the stellar models, and in thiscontext the correct treatment of the transport of chemical elements is crucial.Unfortunately, in many respects calculations of the evolution of the chemicalabundance profiles in stars are still affected by sometime sizableuncertainties. Here, we review the various mechanisms of element transportincluded in the current generation of stellar evolution calculations, how theyare implemented, the free parameters and uncertainties involved, the impact onthe models, and the observational constraints.
