Dessart et al., demonstrated that type II supernova (SN II) model spectra present increasing metal line strength with increasing progenitor metallicity. To confront these models with observations, we obtained a large sample of SN II host H ii region emission line spectroscopy. We show that inferred SN II host H ii region metallicities have a statistically significant correlation with the strength of SN II metal lines, specifically Fe ii 5018Å.
