The Millwright Test is for use in selecting millwright candidates who have knowledge in the following areas: Hydraulics & Pneumatics; Burning & Fabrication and Print Reading; Power Transmission & Lubrication; Pumps & Piping; Rigging; Mechanical Maintenance; and Shop Equipment & Tools, Materials & Equipment.  The Millwright Test was developed in 1989 as part of the development of a series of skills tests. This shortened version consisting of 60 items, was developed in a self-scoring format in July of 2000.

This test contains 60 items in a multiple-choice format. In a group of 84 candidates, reliability was .86 with a mean score of 36.0, a standard deviation of 9.13, and standard error of measurement of 3.42.

The test was intended for use with applicants and incumbents for jobs where millwright knowledge and skill are necessary parts of job activities. Job analysis activities conducted during development of this test revealed that an applicable titles are Millwright (any industry) and Maintenance Mechanic (any industry) as defined in the Dictionary of Occupational Titles (U.S. Department of Labor, 1991).

We recommend that test validation be conducted for an organization that meets any of the following criteria:

  • Is a highly visible national or international company
  • Has more than 200 employees
  • Has a labor agreement
  • Has a federal contract
  • Has ever had an EEO charge
  • Needs professional assistance for setting cutting scores on tests

The Uniform Guidelines on Employee Selection Procedures (1978)1, developed by the EEOC, Civil Service Commission, Department of Labor and Department of Justice, are intended to establish a uniform Federal position in the area of prohibiting discrimination in employment practices. Regarding the use of tests and other selection procedures, the Guidelines state:

These guidelines apply to tests and other selection procedures which are used as a basis for any employment decision. Employment decisions include but are not limited to hiring, promotion, demotion, membership (for example, in a labor organization), referral, retention, and licensing and certification, to the extent that licensing and certification may be covered by Federal equal employment opportunity law. Other selection decisions, such as selection for training or transfer, may also be considered employment decisions if they lead to any of the decisions listed above. (Section 2B)

The Guidelines also state:

The use of any selection procedure which has an adverse impact on the hiring, promotion, or other employment or membership opportunities of members of any race, sex, or ethnic group will be considered to be discriminatory and inconsistent with these guidelines, unless the procedure has been validated in accordance with these guidelines. (Section 3A)

From the employer’s perspective, it is very useful to have a job-related test. When tests are job related, they have more credibility with the persons taking them, giving the test takers more confidence in their results and providing less likelihood of complaint or litigation. A validated test is usually the product of research by a psychologist. The resulting validation report is the documented evidence by a professional researcher of the validity of the selection procedure. In the event of complaint or litigation, the report would usually be entered into evidence. In addition, the author would provide testimony that the report reflects generally-accepted professional practice and is in conformance with the requirements of the Uniform Guidelines on Employee Selection Procedures.
