Quark-hadron duality reflects the relationship between the quark and hadron descriptions of hadronic processes and is related to the nature of the transition from non-perturbative to perturbative QCD. The phenomenon of duality can be studied in a variety of processes, such as e⁺e^- annihilation, deep inelastic scattering, heavy quark decays, etc. Recent data on inclusive electron-proton and electron-deuteron inelastic scattering obtained at Jefferson Lab were utilized for precision tests of quark-hadron duality. These results will be presented, together with future plans of testing/expanding the concept of quark-hadron duality at Jefferson Lab.
