# Plumbing (Commercial, Short) Assessment

## Description
The Plumbing (Commercial) (Short) test is an employment assessment designed to measure the knowledge and skills necessary for entry-level to mid-level commercial plumbers to perform installation, maintenance, and repair of plumbing systems in commercial properties. The test evaluates candidates across key areas including Pipe Materials, Fittings, and Joining Methods; Reading and Interpreting Blueprints and Plumbing Plans; Drainage, Waste, and Vent (DWV) Systems; Commercial Plumbing Codes and Regulations; Identifying and Repairing Leaks, Blockages, and System Failures; and Valves, Water Heaters, and Mechanical Equipment. It measures skill-based competencies through a variety of question formats, including Multiple Choice, Multiple Correct Answer, and Essay Composition questions.
