We use the newest generation of the Starburst99/Mappings code to generate an extensive suite of models to facilitatedetailed studies of star-forming galaxies and their interstellar medium properties, particularly at low metallicities.The new models used include a rigorous treatment of metal opacities in the population synthesis modeling andmore detailed dust physics in the photoionization code. These models span a wide range of physical parametersincluding metallicity, ionization parameter, and the adoption of both an instantaneous burst and continuous starformation history (SFH). We examine the agreement between our models and local (z < 0.1) star-forming galaxypopulations from several large data sets, including the Sloan Digital Sky Survey, the Nearby Field Galaxy Survey,and samples of blue compact galaxies and metal-poor galaxies. We find that models adopting a continuous SFHreproduce the metallicity-sensitive line ratios observed in the local population of star-forming galaxies, includingthe low-metallicity sample. However, we find that the current codes generate an insufficiently hard ionizing ra-diation field, leading to deficiencies in the S it fluxes produced by the models. We consider the advantages andshortcomings of this suite of models, and discuss future work and improvements that can be applied to the modelingof star-forming galaxies.
