General Consultant Knowledge Exam
This exam tests knowledge common to all components of the building envelope (roofing, waterproofing and exterior walls). This was designed to produce a more efficient testing process, eliminating common information being tested for each consultant designation. To earn the RWC designation, a candidate must pass the general exam as well as the RWC Exam. However, applicants who currently hold the Registered Roof Consultant (RRC) and/or Registered Exterior Wall Consultant (REWC) designation(s) are exempt from taking the GCK Exam.
If only one of the two exams is passed (the general or the technical), the candidate will be required to retake only the exam he or she failed. The exam that has been passed will be valid until the candidate passes the other exam and the first consultant designation is earned. Candidates who do not pass an exam will have the option to retry every four months with a valid application.
The exam is computer-based and offered at over 1,000 conveniently located testing locations. Visit Scantron for testing center locations. The exam is 4 hours in length and consists of 90 multiple-choice questions which test knowledge in the following general consulting areas: ethics, general skills, communications and reports, codes and standards, design processes, procurement processes, agreements, and construction administration.
All questions pertain to consulting practices in general and are applicable to all consultants, in spite of the discipline (roofing, waterproofing, exterior walls).
