Together with the iThemba Foundation, Onsea House believes in supporting the communities’ development through raising its academic standards. The school serves almost 2000 students, from ages 5 through 18 years old (the older students are part of the school’s MEMKWA programme for those who were never offered an education or those who had to drop out of school at a young age for a myriad of reasons).

We have volunteer teachers from around the world working within all of our departments as well as Baraa’s unique SEN (Special Educational Needs students) unit.
