NOvA is a two detector long-baseline neutrino oscillation experiment using Fermilab's 700 kW NuMI muon neutrino beam. It studies the disappearance of muon (anti)neutrinos and the appearance of electron (anti)neutrinos in the beam over a distance of 810 km between the detectors. The observations can be used to constrain neutrino oscillation parameters: θ 23 , ∆m 2 32 and δ C P in the standard 3 active neutrinos paradigm. Although statistical uncertainties currently dominate in these

This note presents details of the systematic uncertainties affecting NOvA's neutrino oscillation analysis results and how we evaluate them by generating systematically shifted predictions.
