InfoComm's Certification Department undertakes a rigorous, step-by-step process to ensure the CTS Exams are fair and relevant.

Each exam is based on that certification's Job Task Analysis (JTA), a document laying out the general skill domains, tasks, steps, and knowledge expected of certified professionals. All exam questions are based on topics identified in the JTA. You can download the JTA for any CTS certification from InfoComm's Certification department website, www.infocomm.org/certification.

The Exam Content Outline is derived from the JTA. It identifies how much of the exam each task identified in the JTA comprises. Task weighting is derived from several factors, including the task's frequency and importance. The Exam Content Outline determines how many questions are developed about each task.

The CTS exams are developed by volunteer subject matter experts (SMEs), working together with professional testing experts known as psychometricians. Volunteer item writers develop the test questions. These item writers base their questions on published, publicly available content, such as books, scholarly articles, and standards. That includes, but is not limited to, InfoComm's own publications, standards, and courses.

It's important to note that InfoComm's Education department never gets to see the CTS exam test questions. If we could, then this course would basically be a cheat sheet for the test. But then the test wouldn't be valid - all it would prove was that you have paid attention in class, not that you were any good at your job. Instead, we base this course on the same JTA and Exam Content Outline used by the item writers to develop the exam. The Education department and the Certification department are working from the same blueprint, but building different houses, and Education doesn't get to peek in Certification's windows.

Once questions are written, they are reviewed by another set of volunteers. Then before being incorporated into the exam, questions are piloted to make sure they're fair. The CTS exams undergo continuous improvement to make sure they're accurate and up-to-date.
