CNC Operator Test

A CNC operator test can be used during the recruitment process to assess candidates on the core skills and expertise required to be a CNC operator.

  • What is a CNC operator test?

    A CNC operator test is used to identify the candidates who have the requisite skills and knowledge in CNC operating. The test is commonly used in the early stages of the recruitment process to ensure the most promising candidates are shortlisted.

    The CNC operator test includes a series of specially designed multiple-choice questions that assess candidates on essential areas required for the role, such as fundamental knowledge of CNC programming and machinery, reading drawings and blueprints, and analytical skills.

    A candidate who scores highly on this test has shown they may have the technical expertise and skill set required to fulfil their duties as a CNC operator to a high standard.

About the CNC Operator Test

A CNC operator produces machined parts by setting up, overseeing and operating CNC (Computer Numerical Control) machines. A CNC operator must have a deep understanding of CNC software and machines, as well as how to keep them running efficiently and safely.

A CNC operator test ensures that a candidate has the technical and soft skills necessary to perform this role effectively. The test provides comparative data that can be used to make more informed, data-driven decisions.

  • Why should you use a CNC operator test for recruiting?

    Shortlisting CNC operator candidates based on resumes and applications alone can be difficult. Without further scrutiny, determining a candidate's level of skills and expertise in CNC operating can be challenging.

    A CNC operator test helps address this problem by providing you with a simple and objective way to assess candidates.

    The test has been specially designed to evaluate candidates on fundamental CNC operator expertise, such as proficiency using CNC software, understanding of how to maintain machinery, and ability to read blueprints. It also tests them on necessary soft skills such as attention to detail, problem-solving, and critical thinking.

    The test is easily distributed to candidates in your talent pool and provides you with a set of straightforward results that can be used to compare candidates on their suitability. This allows you to whittle down your talent pool to a shortlist of only the most promising candidates.

How our test assesses CNC operator skills

Candidates will need to answer a range of questions that measure industry-specific soft skills (e.g. teamwork), aptitude (e.g. mechanical reasoning) and relevant personality dimensions (e.g. detail orientation). The results present a holistic view of how well suited each candidate is for the job at hand, using a data-driven approach.

The format varies by type of question, including multiple-choice for aptitude and technical skills, situational judgement for soft skills and agreement on a Likert scale for the personality dimensions. This approach ensures candidates are being assessed in an accurate and fair manner, and that results reflect the true underlying qualities of each candidate.

The characteristics, abilities and knowledge necessary to be a CNC operator were identified using the US Department of Labor's comprehensive O*NET database. O*NET is the leading source of occupational information that is constantly updated by collecting data from employees in specific job roles.

During the development process, test questions were rigorously analysed to maximise reliability and validity in line with industry best practices. They were created by our team of I/O psychologists and psychometricians – who collaborated with subject-matter-experts – and field-tested with a representative sample of job applicants who have varying experience, just like you might find in a talent pool.

Each test is reviewed by a panel of individuals representing diverse backgrounds to check for any sensitivity, fairness, face validity and accessibility issues. This ensures each candidate has a fair chance of demonstrating their true level of expertise.

Our CNC operator test is monitored to ensure it is up-to-date and optimised for performance.
