WELL Accredited Professional (WELL AP) Overview
These study notes are designed to prepare candidates for the WELL AP exam, which tests knowledge of the WELL Building Standard v2, focusing on strategies to enhance human health and well-being through building design, operations, and behavior. The notes are anchored in official sources including the WELL Building Standard, ASHRAE, and ICC codes. Candidates should verify specific pass marks, fees, and eligibility with the official WELL Certification Institute.
For Technical Conquer practice planning, this module is tracked as 100 questions over about 180 minutes with a listed pass mark of 70%. Treat those numbers as practice baselines and verify the current official format before scheduling.

How To Use These Notes With Practice Questions
Do not jump straight from reading to a full mock. Work by subject first: review the key notes, make a short recall sheet from memory, then answer a focused question set. After each miss, decide whether the problem was missing theory, weak code/source recall, poor measurement setup, calculation error, or a field sequence you did not visualize.
Technical Conquer's question bank, flashcards, mind maps, and spaced review tools are most useful after this instruction layer because they reveal which parts of the notes are not yet retrievable.
Final Review Checklist
- Review all WELL v2 feature tables for each concept.
- Understand the difference between preconditions (mandatory) and optimizations (optional).
- Practice applying WELL requirements to sample building types (office, school, healthcare).
- Familiarize yourself with performance verification test methods and thresholds.
- Review ASHRAE standards (62.1, 55) and IESNA lighting guidelines as referenced.
- Ensure you know the WELL AP exam format and verify details with the official body.
