Intercultural Communication Competence (ICC)
entry by Julie M. Marx, Global Family Expert at Expat Valley
The capacity to communicate effectively and appropriately with people from different cultural backgrounds, integrating knowledge of cultural difference, sensitivity to contextual variation, and behavioral flexibility in real-time interaction. ICC is the communication-specific dimension of the broader intercultural competence construct, emphasizing that cultural effectiveness is fundamentally enacted through communication — verbal, non-verbal, and relational.
Comparable terms
IC (Intercultural Competence — the broader parent construct; ICC is the communication-specific subset) · IPC (Interpersonal Communication Competence — the non-cultural equivalent; distinguished from ICC by its lack of cultural specificity) · Cross-cultural communication (general descriptor — widely used; less theoretically precise than ICC) · Communicative competence (Hymes — the foundational linguistics concept from which ICC partially derives)
Why this matters
ICC is where intercultural theory becomes everyday conversations, emails, and classroom interactions. It determines whether good intentions actually feel respectful to others. Developing ICC is one of the most practical investments for globally mobile families and professionals.
Cross-references
Intercultural Competence (Cultural Adaptation); DMIS (Cultural Adaptation); CQ (Cultural Adaptation); Cultural Agility (Cultural Adaptation); EQ (Cultural Adaptation); CCT (Cultural Adaptation); Code-Switching (Language & Identity). Cultural agility is the behavioral meta-competency of which ICC is a primary component; EQ is the interpersonal emotional foundation on which effective intercultural communication is built. CCT is the structured intervention most commonly designed to develop ICC alongside broader intercultural competence. Code-switching documents the specific linguistic practice through which ICC is most visibly enacted in multilingual cross-cultural contexts.
