The number of Irish-language post-primary schools in Northern Ireland is set to double under plans published by the Education Authority (EA).
This would mean an increase from two to four Irish-medium post-primaries, with a new school in Belfast and in the west of the region.
Two new special schools and a number of new integrated schools are also planned in the next few years.
But some other schools could eventually close or merge.
This is due to a longer-term decline in pupil numbers.
