The Plumbing (Residential, Short) test is designed to evaluate the knowledge and skills necessary for entry-level to mid-level residential plumbers to perform installation, maintenance, and repair of plumbing systems in homes. The assessment covers key areas including Pipes, Fittings, and Connections; Drain, Waste, and Vent (DWV) Systems; Fixtures: Installation and Repair; Water Supply Systems and Pressure; Water Heater Installation and Maintenance; and Leak and Clog Diagnosis and Repair. It measures skill-based competencies through a variety of question formats, including Essay Composition, Multiple Choice, and Multiple Correct Answer questions. To enhance the integrity and predictive value of the assessment, questions are drawn from a large pool to reduce the risk of cheating, and one or more questions include time limits. Additionally, artificial intelligence is used in the scoring of one or more questions, ensuring a thorough and modern evaluation of each candidate's residential plumbing knowledge and capabilities.

The specific attributes measured include:

Following completion, the test produces a Candidate Selection Report that includes an overall score and detailed scores for each attribute.

The Candidate Selection Report also provides expert interview questions that help you probe critical or low-scoring areas, along with a guide for noting your evaluation of the candidate's responses. Consistent use of an interview guide is an important part of gaining better candidate insights and making better hiring decisions.

Note that while the Plumbing (Residential, Short) assessment is a useful and efficient instrument for confirming a base level of skill or knowledge about this important topic, it is not intended to pinpoint the exact level of candidate or skill. We recommend that skills tests, like this one, be used in parallel with other measurements, such as cognitive ability, job fit, and behavioral history. Each different type of test provides a valuable piece of information you can use when evaluating potential job performance.
