We present the results of an analysis of on-orbit data from the Cosmic Ray Energetics And Mass instrument for the International Space Station. The design objective is to measure the elemental spectra of cosmic rays from Z=1 to Z=26 over the energy range of $10^{12} - 10^{15}$ eV. The instrument was installed on the ISS on August 22, 2017 with operations terminated on February 12, 2019, resulting in approximately 1.5 years of operation. We compare detailed GEANT4 simulations to instrument data, demonstrate how we determine the appropriate energy scale for the instrument, and show some preliminary results.
