The International Cricket Council has announced the format by which Ireland and Scotland will bid to qualify for
The 16 hopeful teams will battle for two tournament places in a 12-day event in the United Arab Emirates in March.
Ireland and Scotland are in Group B with Kenya, Namibia, Uganda, Oman, Italy and the United States.
Group A comprises Afghanistan, the Netherlands, Canada, Papua New Guinea, Hong Kong, Bermuda, Denmark and Nepal.
The two group winners of the ICC World Twenty20 Qualifier will play each other in the first qualifying final, with the winner of that game guaranteed a place in the tournament proper.
Group A's second-placed team will play the third-placed team in Group B and vice versa, with the winners of those games meeting in the preliminary final.
The preliminary final winner and the first qualifying final loser will take part in the second qualifying final for the second place in the main tournament.
The winners of the two qualifying finals will then contest the ICC World Twenty20 Qualifier final - with the winner joining Australia and West Indies in Group B of the tournament proper, and the runner-up facing defending champions England and 2007 winners India in Group A.
This will be the third time ICC associate and affiliate teams have had the chance to qualify for the World Twenty20, with the 2012 event taking place in Sri Lanka from 18 September until 7 October.
