CSI CDT

CSI organizes the exam around four knowledge domains: construction documentation development and administration, specification writing and enforcement, product research and sourcing, and communication with the design and contracting teams. Each carries 25 percent weight in this profile. The emphasis is on how documents are produced, coordinated, and used across the project, not on memorizing one trade's technical details.

No. The only stated requirement is a high school diploma or equivalent. CSI highly recommends two years of experience in construction management and/or completion of college-level coursework, but describes that as a recommendation rather than a condition of eligibility. Candidates with less experience should plan more study time to absorb project roles and document flow.

Start with documentation development and administration, because it gives you the project-phase framework the other domains hang on. Then take specification writing and enforcement, followed by product research and sourcing, which depends on understanding how specified products are described. Finish with communication with the design and contracting teams, which ties the earlier material together through roles and coordination.

Weak grasp of how the documents interrelate. Candidates who study each document type in isolation often cannot answer questions about which document governs, who acts first, or where information belongs. Build a mental map of the project lifecycle and practice tracing a single requirement from drawing to specification to contract administration before exam day.

CSI publishes upcoming exam dates and registration through its certification pages, alongside a free candidate handbook and study resources. Organizations with 10 or more certification applicants can contact CSI about group registration and pricing. International candidates should note that CSI administers exams remotely and requires passport identification in English.

CSI offers a free CDT candidate handbook, a knowledge domains page, exam preparation source materials, and a published exam schedule. CSI also publishes recertification information and learning unit guidelines for maintaining the credential. Start with the handbook and knowledge domains, then use the source materials list to build a reading plan before scheduling your exam.

CSI positions the credential for people new to the AECO industry as well as experienced professionals, and publishes success stories from candidates at different career stages. It signals that you can interpret and communicate construction information, which is useful when you are competing for project-team roles. Weigh the study time against how much document coordination your target role involves.

CSI issues digital badges and maintains certification records accessible through its certification portal. The credential is not permanent: CSI publishes recertification requirements and learning unit guidelines, so plan to track continuing education. Check CSI's recertification pages for the current cycle requirements rather than relying on older figures, since CSI revises these periodically.

The CDT is the broad, foundational credential covering how construction documentation is interpreted and communicated. CSI's CCCA focuses on developing, administering, and enforcing construction documentation; the CCS validates specification writing and product research skill; and the CCPR is aimed at product representatives. Many people earn the CDT first and add a specialized credential later.
