Rating Scale and it’s characteristics

Definition of rating scale

As per Gibson & Mitchelle – “Rating scales are for rating each of the characteristics or activities one is seeking to observe or assess.”

As per Bonny and Hampleman – “A rating scale is a special kind of checklist in which the items or characteristics checked must be rated quantitatively or qualitatively according to the degree of presence or absence of a trait, the degree of perfection of a skill or a degree of completion of a task.”

Characteristics of rating scale

  • Rating scale is the judgement of one person by another
  • It is a directed observation
  • It is opinion of some object, situation or character
  • It systemizes the expression of opinion concerning a trait.
  • A systematic procedure for obtaining, recording and reporting observer’s judgements.
  • It is a subjective method through which we can find out opinions about a particular person.
  • Similar to a Check List but with finer discriminations.
  • It may be filled during or immediately after or much later after the observation is made.
  • Ratings are done by parents, guardians, teachers, students themselves, friends, a board of interviewers, judges, and by the self as well.

Types of rating

  • Descriptive Rating – The characteristics or traits or qualities are described in words or phrases. The Rater puts a tick in the blank or bracket in front of the quality.

Eg. English Teaching –

I can’t understand (  )

It is difficult to understand (  )

Clearly understood (  )

  • Numerical Rating – Numbers assigned to each trait.

Eg. I like to co-operate –

0 – For Never

1 – Sometimes

2 – Rarely

3 – Often

4 – Always

  • Graphical Rating – Similar to descriptive scale and the difference lies only in the way it is written.

Eg. Responsibility for completing work

Very High–  High —  Average–  Low–  Very Low

  • %age of group scaling – Rater is asked to give the % of the group that possesses the trait on which the individual is rated.

Eg. Self-confidence of the individual

1 to 10 %

11 to 25%

26 to 50%

51 to 75%

76 to 100%
