CABA Certified Commissioning Professional (CCP) Overview
These study notes are designed to prepare candidates for the CABA Certified Commissioning Professional (CCP) exam. The CCP credential validates expertise in building commissioning, covering pre-design through post-occupancy phases. The notes are anchored to official sources including ASHRAE, ICC codes, and commissioning body standards. Candidates should verify specific exam details (e.g., pass mark, format) with CABA or the testing body.
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.
