ABSTRACT
At first glance, a psychologist may see nothing more in a test standardisation than a public service at its best faithfully but banausically performed. The standardisation of a test with 16 independent factors is a more complex undertaking than that of a single intelligence test. While imagination could readily move over the possibilities, one must not forget that the primary purpose of the standardisation is to give the most dependable service in the use of the 16PF in education, clinical psychology, vocational guidance and other fields of applied psychology. The 16PF standardisation samples differ from both Target Group Index (TGI) and the Registrar General's Estimates by the exclusion of the illiterate and more seriously infirm. In this last respect too, the scientist of imagination and vision will see in the present standardisation something far more significant than the calibrating of just any psychometric testing scale.
