As a certification organization, CCI’s role is developing and administering certification examinations. CCI does not require or endorse any specific study guides, review products, or training courses. Candidates may prepare for certification examinations with any educational materials they choose. Purchase of CCI review materials is not a requirement for testing, nor does use of any review materials (CCI or otherwise) imply successful performance on the certification examinations. No study resources are prerequisites for the certification examinations.
