DUNE (Deep Underground Neutrino Experiment) is the future long-baseline neutrino experiment in the US, with the primary goal of precisely measuring leptonic CP violation.

To make precision neutrino oscillation measurements, the energy of each interacting neutrino must be precisely determined. This is difficult due to our understanding of the outgoing leptonic and hadronic final states of neutrino-nucleus interactions, particularly the fraction of "missing" energy due to unseen neutrons and low energy hadrons. The DUNE-PRISM measurement program provides an experimental solution to the neutrino energy measurement problem by moving the near detector complex to a variety of angles off-axis to the neutrino beam direction, which provides a suite of measurements of neutrino-nucleus interactions at a variety of different incident neutrino energy spectra. This extra degree of freedom allows for the association of incident neutrino energy to the distribution of the experimental observables without heavily relying on neutrino-nucleus interaction modeling. The current status and future prospects for DUNE-PRISM will be discussed.
