By moving societies toward globalization and the expansion of competition in the industrial product market, human resource efficiency more than ever has become the determining factor in the competitiveness of industrial products in domestic and foreign markets and thus the profitability of the industry. The main objective of this study is to identify and explain the factors affecting the efficiency of human resources in the processing industry (rice) in Guilan Province. The research method is descriptive and analytical. The study sample consisted of officials and personnel working in rice mills that have at least a high school diploma and experts on rice processing industry in Agriculture Organization that, according to the relevant authorities, 3750 people in rice workshops and 130 people are working in the Agricultural Jihad Organization in Guilan Province. Out of these, a sample of 350 participants were selected by stratified and cluster sampling. To collect data, labor productivity questionnaire and ACHIEVE model containing 24 items were used. The validity of this study was estimated by a Cronbach's alpha, which was equal to 0.90 and was indicative of high validity of the questionnaire. To analyze the data, one sample t-test was employed using SPSS software. The results of the study revealed that employees had the required ability, understanding, organizational support, motivation, feedback, reliability, and compatibility. The results also suggested that there was not statistically significant difference between men and women in terms of the productivity of human resources. Human resources productivity was different between different age groups. According to the average productivity of human resources in different age categories, the average productivity of human resources among people ranging in age from 20-30 years was more likely than others. Variance analysis comparing the average of the four groups (diploma, associate degree, undergraduate, and graduate) with a significant level up to 0.05 showed that there was no statistically significant difference between people with different educational levels with the efficiency of human resources.
