The process of trying to find a relationship factor analysis (interrelationship) between a number of variables are mutually independent with each other, so that it can be made of one or a set of variables is smaller than the number of initial variables. Based on the results of research conducted at SMAN 1 Medan by using factor analysis method obtained three factors that affect student achievement. The first factor is the dominant factor in the student and the environment (33.721%), the second is the supporting factor (14.176%) and the third is an additional factor (11.248%). With the amount of variance of the third factor of 59.145%.
