As a certification organization, CCI's role is in developing and administering certification examinations to determine the qualifications of candidates for certification. CCI does not require or endorse any specific study guides, review products, and/or training courses to prepare for its exams. Candidates may prepare for certification examinations with any educational materials they choose. CCI offers various study resources for the certification examinations such as an online practice exam, sample questions, and flashcards. No study resources are prerequisites for the certification examinations. 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.
