AACE Certified Cost Technician (CCT) Primer Practice Exam 2025 - Free CCT Practice Questions and Study Guide

The correct response emphasizes the importance of having adequate knowledge and honest conviction before expressing opinions on cost engineering or management. This principle aligns with the ethical standards of professional practice in the field.

Possessing adequate knowledge means the individual should have a solid understanding of cost engineering concepts, methodologies, and the context related to the issue at hand. This knowledge allows them to provide informed, credible opinions that can withstand scrutiny. Honest conviction is equally vital, as it signifies that the person genuinely believes in what they are stating, which helps to maintain integrity and fosters trust among peers and stakeholders.

While expert qualifications may enhance credibility, they are not strictly necessary for expressing informed opinions unless they imply a formal recognition of expertise through credentials or specific experience. Strong evidence and credible witnesses could support opinions but do not inherently qualify someone to express them. Simply having evidence or witnesses does not substitute for the foundational requirements of knowledge and genuine belief in what one is communicating.
