PCI have been in a relationship with PCEA since the mid-1960s. First to go were Dick and Moreen Gordon, who went in 1966. Since then, more than 20 long-term mission workers, as well as numerous short-term volunteers and teams, have served with PCEA in Kenya. PCI are currently supporting three families in Kenya; all are serving with PCEA in different parts of the country.

PCEA regularly sends ministers to study in the UK and Ireland, supported by scholarships from PCI. Annual grants are provided for the work of theological education and student scholarships at the Presbyterian University, Kikuyu and St Paul’s United Theological College; and for lay-training and Theological Education by Extension.
