### Description

The Karlsruhe Tritium Neutrino (KATRIN) experiment aims to make a precision measurement of the effective neutrino mass by leveraging the kinematics of tritium beta decay, with a sensitivity of 0.2eV (90% C.L.). Recent run campaigns, both in standard mode (using molecular Tritium) and calibration mode (using $^{83m}$Kr) operation, have provided a wealth of data. The models which we use to fit these data include information about the decay physics, and is convolved with a response function, which encodes details of the experimental setup into the model. In order to achieve the design sensitivity levels, our understanding of systematics must be under control. To this end, we explore KATRIN systematics and their effects on certain model fit parameters. A summary of preliminary results will be given here, as well as an outlook to both the immediate and extended future.
