Introduction: recent studies emphasize the importance of examining the effect of socioeconomic status on child psychomotor development. In this sense, research conducted reports that the level of economic and cultural environment child operate in, are crucial for facilitating their normal development. Objectives: the study proposes a statistical model to predict the psychomotor development score of children from 4 to 5 years of age depending on the socio-economic level. Methodology: psychomotor development was evaluated in a sample made up of 228 boys and girls through the application of the psychomotor development test (TEPSI). A demographic survey was applied to parents and guardians to determine their socio-economic level. A non-parametric bivariate correlational analysis was performed, and a single factor ANOVA tests were carried out. Last, a multiple regression analysis was made for modelling purposes. Results: the results reported that the educational level of the head of household and the per capita income is significantly correlated with the psychomotor development. Conclusions: as to models, the possibility of designing three models is reported. The first one allows predicting 4.2 % of the psychomotor development score based on the per capita income variable. The second model is able to predict 11% of the language score based on the per capita income variable. Last, the third model, with low predictive value (2.2 %), enables predicting the coordination score, based on the educational level of the head of household.
