Pedestal stability is investigated using the ELITE code for several SPARC scenarios of interest, including 1) Primary reference discharge (PRD), 2) Full field reduced confinement H-mode (H07), 3) Full field high density (HIDEN), and 4) 8T H-mode (8T). Dominantly unstable toroidal mode numbers and growth rates are calculated along with peeling-ballooning eigenmode structures spanning the pedestal region. Potential profiles for each scenario are presented along with self-consistent plasma equilibria. Additionally, sensitivity of growth rates to Alfven normalization as well as ion diamagnetic stabilization for several variations in pedestal profiles is explored
