CARTA's commitment to sustainability and scalability has yielded notable outcomes over the years as a result of the capacity-building interventions in its African partner universities. To ensure its interventions are integrated into institutional practices, CARTA has organized workshops in its partner institutions (referred to as CARTA Joint Trainings) as well as Trainer of Trainers (referred to as CARTA Joint ToTs) targeting faculty members in the institutions. These interventions include the PhD Training, Supervisory Skills, Grant Writing Workshop, and Institutional Support workshops.

As part of the rigorous mainstreaming efforts, the program has also been supporting its partner institutions to hold trainings and ToTs for their faculty members (referred to as Institutional Trainings and ToTs). Additionally, partner institutions have successfully integrated aspects of CARTA curricula into their research training programs and PhD training practices. These components are now included in their PhD training and have been or are in the process of being approved by the relevant governing bodies at these institutions.
