Aim of this study is to assess how the change of socioeconomic gradient and the quality of care environment influence the average and the differences in psychometric domains of ASQ3 in preschoolers. Method: We assessed the psychometric parameters of all preschoolers enrolled in some of day cares in Vlora city, Albania using the ASQ3. We also assessed the quality of care environment according to ECERSR and the socioeconomic status upon the fathers occupation. Results: In the end of this research we found that not only a considerable percentage of preschoolers included in this study have psychomotor delays, but also that these delays and the average of psychomotor development have a significant relationship with the environment factors, as socioeconomic status and care environment. Conclusions: Children development depends more on instructing capacities of kindergartens staff than mothers. So the public health workers should work more with mothers in this direction, focusing in the lowest socioeconomic classes., Aurela Saliaj, Ermira Kola, Lorena Lazaj, Majlinda Rakipaj, Emiljana Çorraj, and Literatura
