The human factor represents an essential component for sustainable development. It is the target of the development process and the beneficiary of its positive effects. On the other hand, it is the main supplier of production, what makes the human resource the real wealth of poor countries as well as the most important factor for the efficiency and success of agricultural development programs of those countries. The agricultural quarantine is regarded as the first line of defense to protect countries against imported infections and pests, as well as protecting consumers against agricultural commodities that are not conforming to standards and specifications. In 2015, the rate of exports and imports examined by Egyptian quarantine was estimated to be 57% of total agricultural exports and imports, a matter that initiates the importance of studying the efficiency of the employees working in the agricultural quarantine in performing the required role in the agricultural development process. The research aimed mainly at identifying the efficiency of Egyptian quarantine workers based on the models of the regression of the dependent variable, “probability regression model", that is Logit - Probit - Poisson - Tobit Regression. The research is conducted in 2017, preliminary data is obtained by questionnaire, 70 cases of workers in the Egyptian quarantine from a total of 789 workers having a bachelor degree or more - i.e. representing about 10% of the total number of employees in Quarantine- have been participated. The results of this study show that an increase in wages by one pound leads to increase the possibility of workers efficiency in the agricultural quarantine by, 0.002 units, according to Poisson model. An increase in the years of age by one year leads to increase the possibility of workers efficiency in the agricultural quarantine by about, 0.214 unit according to Poisson model. An increase in the educational level by one level leads to increase the possibility of workers efficiency in the agricultural quarantine by about 0.155 units according to Poisson model. An increase in the element of training by one unit leads to increase the possibility of workers efficiency in the agricultural quarantine by about 0.089 units according to Poisson model.
