Ultimately, measures in research, testing, assessment and evaluation are used, or have implications, for ranking, intervention, feedback, decision-making or policy purposes. Explicit recognition of this fact brings the often-ignored and sometimes maligned concept of consequences to the fore. Given that measures have personal and social consequences and impact, it becomes important to evaluate the intended consequences and unintended side effects of measurement when validating the inferences and uses made from tests. The mere act of measuring or testing engenders consequences. For example, the naming of a test or subtests reflects our values and may influence how we think about or make use of a construct. The purpose of this note is to provide some remarks on the collection of papers in this special issue and draw attention to consequences and side effects of testing, a topic the authors believe is not highlighted enough in this collection of papers.
