Important exam-number correction: Chicago 307 is the Concrete Masonry Contractor C Card examination. Chicago 302 is the separate Brick Masonry Contractor B Card exam.

Chicago 307 Concrete Masonry Contractor Exam Overview

The Chicago 307 C Card examination is administered through Continental Testing Services for the City of Chicago. Candidates are tested on practical concrete construction, reinforcing steel, materials, tools, estimating, safety, quality control and formwork.

Unlike many contractor licensing exams, the Chicago Concrete Masonry Contractor exam is closed book. That means your exam prep needs to move beyond reference lookup and toward real recall, calculation practice and timed testing.
