Real items, with the answer marked and the reason written out — the same format as all 24.

Procurement & Contracting Requirements

A candidate passes the NASCLA Accredited Commercial General Building Contractor examination. What does passing it accomplish toward licensure?

  1. AIt grants a contractor license automatically in every accepting state
  2. BIt replaces the need for any state license
  3. CIt satisfies the trade/technical portion in accepting states; each state's business and law licensing requirements still apply separatelyCorrect
  4. DIt satisfies both the trade and the business/law requirements in one exam

Why: The NASCLA Accredited exam covers the commercial building trade/technical knowledge and is accepted for that portion by roughly 18 jurisdictions. It does not license the candidate by itself: each state's separate business and law exam, financial, and application requirements still apply.NASCLA Accredited Program scope

General Requirements

In the CSI MasterFormat used to organize commercial specifications, what does Division 01 cover?

  1. AElectrical
  2. BGeneral Requirements, such as administrative, procedural, and temporary-facility provisionsCorrect
  3. CFinishes
  4. DConcrete

Why: Division 01, General Requirements, covers the administrative and procedural provisions that apply across the whole project, such as submittals, temporary facilities, quality control, and closeout. The trade-specific work is in later divisions (for example, concrete, masonry, metals).CSI MasterFormat Division 01
