We present metallicities for 15 Small Magellanic Cloud (SMC) star clusters. We add to this information the ages and metallicities of 15 additional star clusters previously studied by Parisi et al. (2009, AJ, 138, 517) and Parisi et al. (2014, AJ, 147, 71), which were observed and analyzed following the same procedures as in the present work. Therefore, we compiled a sample of 30 SMC star clusters homogeneously studied. Metallicities are determined from the Calcium II triplet lines in spetra obtained using FORS2 multiobject spectrograph on the VLT (Paranal, Chile) and ages are determined from Color-Magnitude Diagrams built from photometry on the pre-images. Using this sample, we now here anlyze the chemical properties of the SMC, particularly the Age-Metallicity relation.
