Systematic effects from quasielastic, resonance production, and multi-nucleon contributions.

Recent results from MINERvA and MiniBooNE are driving a new cycle of model building and testing. Our expectation is that the large 20% uncertainties attached to the output of neutrino event generators will be reduced soonest for QE and QE-like processes. Continued work on delta resonance production may yield similar improvements shortly after. This proceedings paper, and the discussion at the workshop, offer an optimistic reading of this continuing effort. [ABSTRACT FROM AUTHOR]
