Illinois has adopted the Career Cluster model developed by the States' Career Clusters Initiative (SCCI) established by the National Career Technical Education Foundation (NCTEF).
Career Clusters are groupings of occupations/career specialties used as an organizing tool for curriculum design and instruction. Occupations/career specialities are grouped into the Career Clusters based on the fact that they require a set of common knowledge and skills for career success. The Knowledge and Skills represented by Career Clusters prepare learners for a full range of occupations/career specialties, focusing on the holistic, polished blend of technical, academic and employability knowledge and skills.
