I survey past literature of ICTD interventions targeting practitioners to identify a common typology that spans domain and context. I use Lave and Wenger’s Communities of Practice (CoP) theory as a way to understand the situated and social aspects of practice and describe how ICTD interventions have often engaged with such communities. I discuss how a CoP lens may intersect with other theoretical lenses in ICTD and related fields, to address issues around concepts of agency, intrinsic motivation, amplification, and sustainability.
