The technical assistance programs have the purpose of transferring knowledge to the Agricultural Production Units -UPA- for their efficient development. However, this knowledge transfer in many cases is not effective, having little influence on the UPAS. In this sense, this article aims to assess the impact that technical assistance programs have had on the performance of UPAs at the regional level by making comparisons between regions. Through multiple linear regression models, the degree of influence of different technical assistance programs on the performance of agricultural production units will be established. The results show that in general these programs have had little impact on the performance of the UPA for each region analyzed.
