Answer to Question 1

TRUE

Answer to Question 2

A graphic rating scale assesses the performance of the worker along one or more scales that have clearly specified intervals, such as a five-point scale ranging from Almost Never to Almost Always. The advantage of this type of scale is that it is relatively easy to construct and use. The disadvantage is that different raters may not agree on the meanings of particular points along the scale.

A behaviorally anchored rating scale (BARS) assesses the performance of the worker along with a graphic rating scale, where the meaning of each point along the scale is carefully defined by examples of specific behaviors that correspond to that scale point. The advantage of BARS is that it specifies points along the scale. The disadvantages are that workers may exhibit behaviors consistent with more than one point along the scale and the scales require a considerable amount of time and effort for an organization to develop and use.

The behavioral observation scale (BOS) is similar to BARS except it also asks raters to indicate how frequently employees exhibit the behavior of interest. The advantages of a BOS are that scale ratings reflect not only what behaviors are performed, but how often. The disadvantage is that a BOS tends to be even more time consuming than a BARS.
