Which of the following is required in order to obtain a mechanical contractor's license?

To obtain a mechanical contractor's license, both passing a written exam and completing an application are essential requirements. The written exam typically assesses an applicant's knowledge of relevant mechanical codes, regulations, and practices which ensures that licensed contractors are competent in their field. It serves to verify that the contractor has the necessary technical knowledge to perform mechanical work safely and effectively.

Completing an application is crucial as it formalizes the request for the license and provides the regulatory body with necessary information about the applicant, such as their experience, background, and business practices. This process helps licensing authorities to evaluate whether the applicant meets all requirements for licensure, including professional experience and adherence to state regulations.

The combination of both elements—passing the exam and submitting a complete application—ensures that only qualified individuals are licensed, allowing for accountability and safety within the mechanical contracting industry.
