Developing a Psychological Test | Best Practices

A psychological test is a standardized measure of an individual’s performance of defined tasks. Developing a psychological test is a highly specialized process and should be undertaken by experienced professionals. Those who are qualified to carry out these test are called psychometricians, most of whom are psychologists with advanced graduate training. The process itself is difficult and lengthy, but we will try to explain it in brief here. Testing is the measurement of human knowledge, abilities, attitudes and personality traits. It is also called psychometrics.

When developing a psychological test, we will refer to the most widely accepted guidelines, based on the international standards for educational and psychological testing. These standards are a joint publication of the American Educational Research Association, the American Psychological Association, and the National Council on Measurement in Education (1999).

Guidelines

The guidelines for test development should be based on sound science and evidence per standard scientific approach. These guidelines lay out a series of procedures that should take place when developing these tests:

     Specify the purpose of the test

     Make frameworks that describe the knowledge and abilities to be tested

     Develop test specifications

     Create test items and scoring rubrics

     Review test items

     Evaluate quality of all items

While developing a psychological test, the planning phase should require a significant investment in time and thought according to Foxcroft. This should be particularly paid attention to when the test is carried out in a multicultural society. Attention needs to be paid while designing the test for cultural relevance and potential cognitive biases.

Principle

There are principles described by Shultz in Psychology that also work today. Proper psychological testing is based on rigorous research and is not the same thing as the quick questionnaires you find in magazines. These tests comprise the following principles:

1.    Standardization, which we have described above

2.    Objectivity should also be key, with biases minimized 

3.    Test norms, which constitute average test scores and it is possible to establish a point of comparison

4.    Reliability, the test should be consistent in its results

5.    The test should measure what it is supposed to

Importance of testing

Testing is carried out worldwide in order determine selection, placement, and to assess whether an individual requires counseling. It is an important gateway into institutions, organizations, and societies. They help shape the destiny of all those who take it and it is important for those who study these tests that they understand their uses and occasional abuse. Learn in particular the history of psychology, which is a compelling and captivating story. Developing psychological tests and assessments may even be traced back to the Chinese imperial examinations, according to Gregory.

Tools

 

You can use test makers available for this very purpose. It should appear to be difficult with all the sources that we have mentioned, but that is what you are supposed to do with a proper psychological test. Test makers have been developed to aid you in this field, and the results you get should be equally rewarding.
