We present a phenomenological model of the quark-hadron transition in neutrino-nucleon scattering. Using recently extracted weak nucleon transition form factors, we investigate the extent to which local and global quark-hadron duality is applicable in the neutrino F{sub 1},F{sub 2}, and F{sub 3} structure functions and contrast this with duality in electron scattering. Our findings suggest that duality works relatively well for neutrino-nucleon scattering for the F{sub 2} and F{sub 3} structure functions but not as well for F{sub 1}. We also calculate the quasielastic, resonance, and deep inelastic contributions to the Adler sum rule and find it to be satisfied to within 10% for 0.5(less-or-similar sign)Q{sup 2}(less-or-similar sign)2 GeV{sup 2}.
