For the shortcomings of current military academies evaluation methods and evaluation system, research the application of Apriori algorithm for cadres assessment in the military academies. From the perspective of data mining algorithms, the author analyzed the application of Apriori algorithm in mining association rule evaluation of military academies professional and technical cadres by using instance, proposed improved Apriori in military academies cadre evaluation according to its specificity. The results show that this method can reduce the computational algorithms to
