Ireland's victory over Bangladesh earned them a place in the ICC ODI Championship rankings table.
Ireland, who had pulled off a major upset against Pakistan in the league stage, prevailed over another Test playing nation as they beat Bangladesh by 74-runs in the Super Eights.
Defeating two Full members gave them the right to qualify for the ICC ODI rankings charts.
"Ireland's name will appear on the official rankings table following its final game in the Super Eight stage of the event, which will take place in Grenada against Sri Lanka on Wednesday," ICC said in a press release.
"Having made up part of the ICC Associate ODI Rankings Ireland now graduates to the LG ICC ODI Championship after defeating two Full members, in accordance with the qualification regulations," it said.
Once an Associate has played at least 10 ODIs in total, it has the opportunity to be promoted to the main table.
To gain this promotion, the Associate must either achieve two wins against Full Members, as Ireland has done against Pakistan and Bangladesh, or achieve one win against a Full member and also have won more than 60% of matches against other Associates.
Currently, the table is made up of the ten Full members plus Kenya.
In accordance with a previous ICC Board decision, Ireland has ODI status until 2009, a status also enjoyed by the top six Associate Members. Kenya, Scotland, the Netherlands, Canada and Bermuda are the other teams in this list.
