What does the classification of tests primarily relate to?

The classification of tests is fundamentally tied to the level and type of training required to administer and interpret them. Certain tests necessitate specialized knowledge, skills, and experience. For example, psychological assessments or complex standardized tests often require professionals who have undergone considerable training in testing principles, statistical analysis, and ethical considerations. This helps ensure that the tests are administered correctly and that results are interpreted accurately to make informed decisions.

While validity and reliability are crucial characteristics of any test, they do not constitute the primary basis for classification. Similarly, although the intended audience and the cost or accessibility of tests can influence their categorization to some extent, they are not the central focus when classifying tests in terms of training and expertise needed. The emphasis on training underscores the importance of expertise in maintaining the integrity and effectiveness of testing practices in various fields.
