It determined that year's club champion of association football in the CONCACAF region and was played from 1 May until 17 September 1978 and all the matches in the tournament were played under the home/away match system. The teams were split into 3 zones (North American, Central American and Caribbean), each one qualifying the winner to the final tournament, where the winners of the North American and Central American zones played a semi-final to decide who was going to play against the Caribbean champion in the final.
