LEED AP ID+C Exam Prep

The LEED AP ID+C professional credential demonstrates advanced knowledge in the interior design and construction phases of commercial building projects. The USGBC + GBCI created this Tier 2 credential for professionals who want to specialize in Interior Design & Construction: Commercial Interiors. You have to have already passed the LEED Green Associate (Tier 1) exam or be willing to take the combo (GA and ID+C). This LEED v4 exam is based on specific Task Domains and Knowledge Areas highlighted in the ID+C Candidate Handbook.
