The research considered related to human factors inherent to the teacher work measured the influence of the independent variable called “Strengthening of Teacher Service Capacities” in the Public Educational Institutions with primary level, considering as a dependent variable “Empowerment to the Management of the School Food Service” as well as in the levels of the variable: “Teacher Participation” and “Good Hygiene and Food Handling Practices”. The objective was to determine if there was a relationship between both variables and the nature of this relationship. In the results of the dependent variable, there was a decrease in the low and regular levels; and an increase in the high level. When the mean comparison test was performed on the results of the pre-test and post-test, the chi-square test determined that in the dependent variable, if there is significant difference so the alternative hypothesis is accepted and the null hypothesis is rejected.
