We have investigated the robustness of stellar population models in order to address the age and metallicity estimation of disc galaxies. We note that the scatter among simple stellar population models by different groups is surprisingly large at ages t \u3c 2 Gyr. The dominant uncertainties in stellar population models arise from convective core overshoot assumptions and the treatment of the thermally pulsing asymptotic giant branch phase and helium abundance may play a significant role at higher metallicities. It is also emphasized that the current composite stellar population models need some implementation of chemical enrichment histories for the proper analysis of the observational data
