The next advancement took place in 1967 when the USA rules were agreed to as the unified rules for international competition and Ireland was chosen for the 1970 World event. Canada were hosts in 1967 where Joey Maher (Ireland) but playing for Canada beat Carl Obert (USA) in the Invitational Singles Championship and the Obert Brothers, Carl and Rudy beat Harry Capperman and Mickey Unroth (Canada) in the Doubles. In the Open Singles World Championship, Stuffy Singer USA beat Steve August USA while in Open Doubles S. Garden and P. Haber USA beat Pantages and Kristopatis USA.

The Irish council members took their charge seriously, with significant fund-raising efforts in 1968 resulting in the construction of a glass showcase court in 1969 in Croke Park. The GAA was highly instrumental in helping with the funding for this court. Top players from the same five countries at the 1964 World event converged on Croke Park in October 1970. Pat Kirby of the U.S. defeated all comers in singles, with Ireland’s Joe Maher earning second place. Ireland’s Richie Lyng and Seamus Buggy went undefeated in doubles to win that crown, with Bob Wilson and Mel Brown of Canada taking second place. This 1970 competition revealed that the showcase court’s design helped make the game much more readily viewed and appreciated by courtside spectators as well as a TV audience.

In spite of the progress made since 1956, the international handball scene went dormant after 1970 until 1984. That year, in honor of the centennial celebration of the Irish Handball Council, Dublin and Clare hosted a World Tournament featuring play on the 60 X 30 court as well as the 40 X 20, in both singles and doubles.

Canada hosted the 1986 event, in Kelowna, British Columbia. This was the first World event to which junior and women players were invited. Joseph Lynch convened the leaders of the various countries represented and reinvigorated efforts to create a functioning governance structure. Vern Roberts (USA) beat Ducksy Walsh (Ireland) in the Men's Invitational event.

Representatives from six countries made the trek to Melbourne, Australia, for the 1988 tournament. This event continued the opportunity for women players to be involved, so the ongoing growth and popularity curve of the World event remained vigorous. Joseph Lynch and Caimin Jones served the World Handball Council as President and Secretary. Danny Bell won the Invitational event, with Naty Alvarado of USA taking second. Kathleen Beddard of Canada won the Women’s title with Sue Carey of Ireland taking second. In Doubles Joe Nendler/Poncho Monreal of the USA defeated John Fleming/Pat Cleary of Ireland. In Women’s Doubles, Lisa Fraser/Kathleen Beddard of Canada took the crown with Sue Carey/Bridget Mythen from Ireland taking second place.

In 1991, Joe Lynch notified the handball world that he would be resigning his position as National Secretary. Joe had been highly instrumental in endeavoring to get International Handball on a sound footing.

Lorcan O’Rourke assumed the position of General Secretary of Irish handball and was present at the 1991 World event which took place in Phoenix, Arizona. This tournament saw 558 entries, a new and impressive record for entrants. Players from Britain joined players from Japan, Australia, Ireland, Mexico, and the U.S. Poncho Monreal of Mexico defeated Canada’s Danny Bell for the Invitational title, while Anna Engele of the US won the Women’s Invitational crown in a tiebreaker over Canada’s Diane Vallee. The Invitational Doubles saw Doug Glatt and Rod Prince of the US defeat Jeff Wilson/Roberto Meneses of Canada.

In June of 1991, Canada’s Bob Pruden took office as President of the World Council, and held this position until 1997, when Caimin Jones of Ireland assumed office.

The 1994 event added a new country—France—to the other national teams that met in Dublin for the eighth international showcase of handball. Once again, the venues were located in Dublin and Clare, with 41 classes of events for Open, age-group, skill groups, juniors, and women. Nearly 1,000 players from around the world made the commitment to play in this impressive event. The Invitational results showed Dave Chapman (USA) winning against Ducksy Walsh (Ire.). In the Women's open: Lisa Fraser (Can.) prevailed over Anna Engele (USA). In the Men’s Invitational doubles: John Bike/Randy Morones (USA) handled Tom Sheridan/Egin Jensen (Ire).

A newly formed ICHA team of eight including two women allowed to play despite Welsh law prohibiting women to play handball.

In 1994, ICHA was then invited to participate in an invitational One wall exhibition to demonstrate competitive one wall in Bray Ireland to the World Council with the team of Paul Williams, Kendall Lewis, Jai Ragoo, Joe Kaplan and Jason Morgan

In 1997 One Wall was officially added to the World Championships in Winnipeg

Winnipeg, Canada, hosted the World event in 1997.
