The Electrical Work (Residential) assessment is designed to measure the knowledge and skills required for entry-level to mid-level residential electricians performing installation, maintenance, repair, and upgrade of electrical systems in homes. The test evaluates candidates and employees across key areas including wiring, wire sizing, and circuits, electrical panels, breakers, and service entrance, outlets, switches, and fixtures, grounding, bonding, and safety practices, the National Electrical Code (NEC) as it applies to residential work, and reading wiring diagrams and blueprints. It measures skill-based knowledge through a variety of question formats, including multiple choice, multiple correct answer, and essay composition questions. To ensure a thorough and accurate evaluation, the test draws questions from a large pool to reduce the risk of cheating, incorporates time limits on select questions to improve predictive performance, and utilizes artificial intelligence to assist in scoring one or more questions.

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 Electrical Work (Residential) 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.
