Hydraulics Understanding
Many machines depend on hydraulic systems to function, so millwrights need a clear understanding of how these systems work. This skill allows them to troubleshoot, repair, and maintain hydraulic equipment effectively.
6 secondary Millwright skills and traits
The best skills for Millwrights include Electrical Knowledge, Fabrication Skills, Safety Compliance, Computer Literacy, Analytical Thinking and Tool Proficiency.
Let’s dive into the details by examining the 6 secondary skills of a Millwright.

Electrical Knowledge
While not the main focus, understanding electrical systems helps millwrights to collaborate effectively with electricians and perform minor electrical repairs when necessary.
Fabrication Skills
Being able to fabricate parts or structures allows millwrights to customize or repair equipment on-site, which can be cost-effective and time-saving in the long run.
Safety Compliance
Adhering to safety regulations and standards protects not only the millwright but also others working around them. Knowledge of safety practices is fundamental to preventing workplace accidents.
Computer Literacy
As technology advances, some machinery includes computerized control systems. Basic computer skills enable millwrights to operate, adjust, and troubleshoot these modern systems.
Analytical Thinking
This skill aids millwrights in assessing situations thoroughly, interpreting data or patterns, and making informed decisions about equipment maintenance or interventions.
Tool Proficiency
With a wide array of tools at their disposal, millwrights must be proficient in selecting and using the right tools for each task. This proficiency can greatly impact the efficiency and quality of their work.
How to assess Millwright skills and traits
Assessing the skills of a Millwright goes beyond merely checking qualifications on paper. Understanding a candidate's mechanical aptitude, blueprint reading ability, and precision alignment skills can be challenging through resumes alone. It's important to delve deeper into their proficiency in welding techniques, rigging knowledge, and how adept they are at problem-solving, especially with complex hydraulic systems.
To confidently evaluate these competencies, skills-based assessments become crucial tools. Instead of relying solely on traditional resumes, consider utilizing assessments that simulate the real-world tasks Millwrights handle daily. Adaface assessments are designed to help you achieve 2x improved quality of hires and an 85% reduction in screening time, by providing insights into a candidate's problem-solving abilities and technical acumen. This approach ensures candidates possess not only theoretical knowledge but also practical expertise in the specific skills your operation requires.
Let’s look at how to assess Millwright skills with these 2 talent assessments.
Millwright Test
Millwright Test evaluates proficiency in mechanical systems and machinery maintenance with scenario-based MCQ questions.
Candidates are assessed on their expertise in precision measurement, understanding of mechanical tools, and capability in blueprint reading. They must also demonstrate knowledge of preventive maintenance and the use of hydraulic and pneumatic systems.
High performers exhibit strong mechanical aptitude and meticulous attention to detail, crucial for dealing with rigging and hoisting tasks. Knowledge of safety protocols is also evaluated.

Problem Solving Test
Problem Solving Test measures a candidate’s ability to process instructions, analyze data, and tackle complex problems or scenarios.
The test evaluates skills in abstract reasoning, critical thinking, and deductive reasoning. Participants must navigate tasks requiring inductive reasoning and pattern matching, complemented by spatial reasoning capabilities.
Candidates who do well demonstrate strong problem-solving abilities and exhibit agile learning capability. These skills are directly related to improving coachability and learning agility.
