Within CTE, a career cluster is a group of professions in the same field of work that share common features. A pathway is a cohort of three year-long industry-related courses that advance in complexity, skill development and application, and career preparedness. There are 16 national career clusters, and 12 of them are present in Chicago Public Schools. Within the BIT Cluster, two clusters exist (Business and IT), and six pathways (Accounting, Entrepreneurship, Game Programming, Networking, Programming, and Web Development).
