Community-based inclusive development (CBID) requires implementation by competent personnel who have varied knowledge and skills, and attitudes that respect the dignity, voice and agency of persons with disabilities. The capacities of personnel on the ground within community-based rehabilitation (CBR) have been studied previously but there are potential changes to the competencies personnel require with the shift from CBR to CBID. This chapter sets out to explore some of the factors which influence decision-making around desired competencies of CBID personnel. Through foregrounding the factors and the interplay between them, we aim to demystify the choices that have been made regarding key competencies of CBR and CBID personnel, with particular reference to South Africa and Zimbabwe. The authors recommend drawing from the discipline of community development with their generic eight competencies developed as an international standard for community development practitioners. The chapter takes a critical look at who decides on the competencies that CBID personnel should have and the power dynamics therein, noting that the voice of persons with disabilities is missing at times. The chapter illustrates the potential constricting influences of the employment environment for CBID personnel, their supervision and that the CBR/CBID sector is often effectively in a silo. We conclude that the challenge for CBID going forward is to avoid the incestuous development of the discipline and the linked competencies of personnel, and to rather embrace the broad, hybrid nature of the community development discipline.
