WELL AP case studies
WELL AP · Put your knowledge to work in context.
The WELL Accredited Professional (WELL AP) is a professional credential administered by the International WELL Building Institute (IWBI) that recognizes individual mastery of the WELL Building Standard. IWBI describes the credential simply as a way to "demonstrate your mastery of the WELL standard," and positions it within its accreditation track alongside designations such as WELL Enterprise Provider and WELL Faculty. The credential is aimed at professionals whose work touches human health in the built environment: architects, interior designers, engineers, sustainability and ESG consultants, facility and real-estate managers, contractors, and public-health or HR leaders who support workplace wellbeing programs. Because WELL is organized as a set of concept categories - IWBI's own site refers to "all 10 categories in WELL" - candidates should expect the exam to test breadth across the standard rather than depth in a single discipline, including how the concepts, features, and verification pathways fit together in practice. The WELL AP case studies are 5 cases and about 3,260 words.
