The team suffered a crushing defeat in its last match to Costa Rica 8–0. In 1961, Haiti joined the CONCACAF, born from the merger of the NAFC and the CCCF. In 1965, Haiti took part in the second edition of the CONCACAF Championship, after being eliminated in qualifying for the inaugural edition (1963 CONCACAF Championship). This continental meeting resulted in a last place finish, losing all five of its matches played; coach Antoine Tassy then resigns. However, he returned the following year again as the team's head coach, and won the "Coupe Duvalier". During the 1967 Qualifiers, Haiti finished first and was undefeated atop of its group, ahead of Trinidad and Tobago. On 16 January 1967, marked its first victory in a competitive match against the Trinidadians, beating them 4–2. However, Haiti in the final round consisting of six teams, finished in fifth place, defeating Nicaragua 2–1 to avoid last place. As part of the qualifiers for the 1970 World Cup hosted by Mexico, Haiti are engaged in group 2, in the company of Guatemala and Trinidad and Tobago. Directed by Antoine Tassy, Haiti was relevant for the first time in qualifying for the World Cup on 23 November 1968, in Port of Spain against Trinidad and Tobago. Haiti will reach rank at the top of the pool with wins against Trinidad and Tobago 4–0 and Guatemala 2–0, one draw against Guatemala 1–1, and one defeat conceded at home against Trinidad and Tobago 2–4 which enabled them to qualify to the second round. They then eliminated the United States before heading to the final round against El Salvador. Haiti lost the opening match at home 1–2, but managed to rebound and win 3–0 in San Salvador before losing again on neutral ground in Kingston in Jamaica, 1–0 in overtime. At the CONCACAF Championship in 1969, Haiti was disqualified from the final round, when it had qualified in the field by beating the United States (the qualifying round is coupled with the qualifications for the World Cup 1970). Instead, the Federation was unable to register its team for the final round on time to the CONCACAF and therefore could not participate in the final round. The 1970s could be considered a golden age for Haitian football, and its status in the region remained very strong, being considered the third strongest team in the CONCACAF after Mexico and arguably Costa Rica. With Antoine Tassy as coach for much of this period, Haiti would emerge as one of the strongest teams in the CONCACAF zone, being pooled with other regionally strong football nations such as Mexico and Costa Rica.
