Abstract

Scores from tests in the same battery are put on scales which are the "same" in some sense, so that certain interpretations are made easier. This is often done when scores for different tests are obtained on different population segments, especially such as newer, more varied batteries of test offerings. It is felt that traditional erroneous expectations about the meaning of scaled scores may be carried over into the new situations and hence certain of these expectations are discussed. It is suggested that when special properties of scales are considered valuable for the users of a new battery, active technical steps beyond those of traditional scaling are required to assure that these values are implemented.
