Psychology is a diverse and exciting field. As pioneers in a relatively youthful science psychologists worldwide strive to improve every aspect of human life, from planning urban construction and zoning to human-computer interaction. Across all disciplines of psychology there is a common thread that unites all researchers and scientists in the field. This unifying discipline is psychometric /psychometrics. In other words, measuring human characteristics from psychological perspective, hence called psycho-metric.
Psychometrics, being concerned with the design and analysis of research and the measurement of human characteristics, has enjoyed a history of rapid growth and development since its origins with the work of Binet in France and Spearman in England, and the earlier efforts of Galton and his anthropometric laboratory. The field of psychometrics has been the genesis of intelligence testing, personality testing, and vocational testing, and has contributed to the emergence of new approaches and methods to psychological measurement based on the demands of society and the emergence of new technology. Psychometricians have also worked collaboratively with those in the field of statistics and quantitative methods to develop improved ways to organize and analyze data. Today all psychologists who conduct research or who develop psychological measures must be concerned with psychometric issues to ensure the validity of their work. These psychometric principles provide the backbone of psychology as an objective science.
Despite the importance and widespread application of psychometric principles there are actually relatively few universities that offer a Ph.D. in Psychometrics and many undergraduate psychology majors are not familiar with the work of psychometricians. This may be due in part to the under representation of psychometricians in academic settings as a result of the wide variety of competitive occupational opportunities open to graduates of psychometric programs.
course the most obvious area in which psychometricians are employed is in
psychological testing. Testing, whether it be of intelligence, personality,
achievement, aptitudes, interests, or proficiency, is a widespread and important
practice in our society. Testing is employed in schools, organizations,
business, government, clinical settings and hospitals, as well as in the
military. The impact of testing on individuals, organizations, and our culture
is substantial and this reinforces the importance of high professional standards
for the development, administration, and interpretation of tests. Due to the
potential impact of testing on everyone's lives the practice of testing is also
controversial and our society depends on the efforts of psychometricians to continue
striving for more valid, reliable, and efficient tests.
Psychometricians are not limited to working within the testing industry however. Many psychometricians are employed in industrial and organizational settings performing job analyses, consumer surveys, developing and validating personnel selection procedures, and performing market research. Positions in private and public consulting agencies, clinical research positions, and positions in managerial and administrative roles are also open to graduates of psychometric programs. Psychometricians can even find employment as researchers in fields only tangentially related to psychology, as statisticians, expert witnesses, and of course, in academic settings as well.
