Towards a comprehensive picture of the star cluster age-metallicity relationship in the Small Magellanic Cloud

We present the results on the age and metallicity estimates of 11 Small Magellanic Cloud (SMC) clusters obtained from CCD Washington CT1T2 photometry. The 11 clusters reproduce the ~2Gyr bursting formation paradigm when entering them into the age-metallicity relationship (AMR). Once these clusters w...
