In 1973 Father James built the SD Karya Dharma School with the help of donors to bring education to the Tamil Catholics. The Karya Dharma building served as a Primary School as well as the centre for social and cultural activities for the people of Kampung Kristen for some years.
On 8 January, 2017, Father James visited the school to wish everyone a happy new year.
