Comparative appraisals of efficacy require not only evaluation of one;s own performances but also knowledge of how others do, cognizance of nonability determinants of their performances, and some understanding that it is others, like oneself, who provide the most informative social criterion for comparison

The difficulty in judging what type of behavior works well arises not only because a given course of action does not always produce the outcomes. Similar outcomes can occur for reasons other than the person's actions, which further complicates inferential judgment. Effects that arise independently of one's actions distort the influence of similar effects produced by the actions, but only on some occasions. Given a strong cognitive set to perceive regularities, even chance joint occurrences of events can be easily misjudged as genuine relationships of low contingent probability

Reasonably accurate appraisal of one's own capabilities is, therefore, of considerable value in successful functioning. Large misjudgments of personal efficacy in either direction have consequences. People who grossly overestimate their capabilities undertake activities that are clearly beyond their reach. As a result, they get themselves into considerable difficulties, undermine their credibility, and suffer needless failures. Some of the missteps, of course, can produce serious, irreparable harm

Accomplishment is socially judged by ill defined criteria so that one has to rely on others to find out how one is doing.

Because of such conjointedness, behavior that exerts no effect whatsoever on outcomes is developed and consistently performed

Behavior must also be adequately assessed under appropriate circumstances. Ill-defined global measures of perceived self-efficacy or defective assessments of performance will yield discordances. Disparities will also arise when efficacy is judged for performances in actual situations but performance is measured in simulated situations that are easier to deal with than the actualities

Very often we developed a better grasp of the subjects than the over worked teachers.
