The physics of neutrinos has seen significant progress in the recent decades, still, several questions remain unanswered and important experimental efforts are currently taking place to try to provide these answers. In order to formulate significant physical predictions from our experiments, high efficiency and purity are required in the measured data. In this talk, we cover the work made on efficiency and purity on simulated data of the Short Baseline Near Detector (SBND) from the Short Baseline Neutrino (SBN) Program.
