This work aims to determine the existence of educational imbalances in higher-education graduates in Colombia. Educational imbalance is defined as the difference between the schooling level and the level required to perform in a job position. When the former is higher than the latter, it implies the existence of over-education; the opposite case implies under-education. The results indicate that 41.87% of graduates have some imbalance with higher numbers of under-educated graduates. Based on a multinomial logit model the variables influencing the probability of being either over-educated or under-educated were identified. Having earned a technician or technologist degree, living in the Central-East region, and work experience increase the probability of being under-educated. On the other hand, being a man and having an increasingly higher schooling increase the probability of being over-educated
