Free LEED AP Interior Design Construction (LEED AP ID C) Exam Questions and Answers
LEED AP Interior Design Construction (LEED AP ID C) is one of the USGBC tests covered here. Three organisations are involved and it is worth knowing which does what: USGBC develops the LEED rating system, IWBI develops the WELL Building Standard, and GBCI — a separate body from both — administers the exams. LEED Green Associate is the foundation credential and the only one with no prerequisite: 100 multiple-choice questions in two hours, needing 170 points out of 200, sat at a Prometric centre or online-proctored, and renewed with 15 continuing-education hours every two years. The specialty AP credentials sit above it and carry heavier continuing-education requirements.
