Rating-scale technology is advancing as evidenced by the publication o
f a second generation of behavior rating scales and checklists. These
instruments are assumed to represent a rater's (teachers, parents, stu
dent) summations of recent direct observations and experiences with ta

ns school psychologists are asked to make about children and education
al services. Therefore, this article reviews many uses of rating scale
s, provides guidelines for selecting and using rating scales, examines
the Achenbach scales in some detail as a way to illustrate points abo
ut usage and development, and concludes with a discussion about advanc
ements in the development and use of rating scales.
