Basic Theories to the Conceptualizations of Job Analysis Accuracy.

There are two basic theory to the conceptualizations of job analysis accuracy:- Classical Test Theory and Generalizability Theory. Classical test theory suggests that a "true score" esists for a given job and that true scores are stavle over time. Any measurement variation error are eliminated or aggragated across time or sources. Through this, researchers have commonly aggregated job analysis information in order the get the "true score" for every particular job, then the quality …

…more than accuracy, and the problems which are associated with making judgments about job analysis data. This eventually means that Sanchez and Levine's (2000) conception doesn't address the difficulties linked with job analysis data to evaluative standard. Because of this, attention are shifted to the consideration of the validity of job analysis inferences. This shift avoided the problems in associated to the discussion of job analysis accuracy, and implicitly includes Sanchez and Levine's (2000) notion of utility.
