Rating scales to assess the level of proficiency of human performance have come in a wide variety of formats. The objectives of the scales, types of questions asked, and procedures followed vary widely. Prior to 1960, most rating scales utilized what is known as the graphic format. According to Guion (1965) the rating scale was relied on in 81% of the validation studies using rating scales. While this has declined somewhat (Landy § Trumbo, 1976) performance ratings still play a major part in validation. This study will compare behavioral observation and behavioral expectation scales in terms of psychometric properties. Central to these scales is the question whether either of the scale development procedures is superior.
