Tabubil International School caters for children of employees of Ok Tedi Mining and their contractors.
The school was forced to close mid-2015 when the mine shutdown operations due to a major drought that hit the nation.
The school has reopened, this time, under the International Education Agency, as confirmed by IEA director of education Suzanne Savage.
Savage says IEA was approached last year as the preferred provider to reopen the school and continue it into the future.
