Direct answer
When requested work changes scope, cost, or time, what should control before proceeding is a TradeCert Prep study concept connected to NASCLA Practice Exam prep, not a copied official exam item. Changed work should be documented and authorized as required by the contract, including its price and schedule effect. Always verify licensing, certification, and testing rules with the current official candidate bulletin, state manual, code book, or testing provider before relying on a detail for compliance.
