Rating scale is an

important technique of

evaluation. Rating is the

assessments of a person

by another person. This is

one of the oldest methods

of personality assessment.

There are certain general

approaches to assess

personality like holistic or

overall approach,

projective test approach

and trait approach. In this

rating scales and

inventories come under

the trait approach.

PIONTS OF RATING SCALE:

• Three point scale

Above average / Average / Below average

• Five point scale

Excellent / Very good / Good / Average / Poor

DESCRIPTIVE

RATING SCALE

IN THIS DESCRIPTIVE TERMS OR PHRASES ARE ASSIGNED TO EACH TRAIL.THE RATER ENTERS THE APPROPRIATE PHRASES AFTER EACH NAME TO INDICATE JUDGEMENT OF THE PERSON.

NUMERICAL RATING SCALE

In which numbers are

assigned to each trait.

If it is a seven point

scale, the number 7

represents the

maximum amount of

that trait in the

individual, and 4

represents the average.

The rater merely enters

the appropriate

number after each

name to indicate

judgment of the person.

ACTIVITY:

HOW FAR DO YOU UNDERSTAND SUBJECTS IN NURSING?

GRAPHIC

RATING SCALE

A straight line,

may be

represented by

descriptive

phrases at various

points. To rate

the subject for a

particular trait a

check mark is

made at the

particular point.

COMPARATIVE RATING SCALE

• IN THIS PERSON MAKES AJUDGEMENT ABOUT AN ATTIRE/ATTITUDE/OBJECT....... BY COMPARING IT WITH OTHERS/RANKING IT.

CHARACTERISTICS OF RATING SCALE:

• 1. These are value judgements about attributes of one person by another person.

• 2.These are most commonly used tools to carry out structured observations.

• 3. These are generally developed to make qualitative judgement about qualitative attributes.

• 4. Provide more flexibility to judge the level of performance.

PRINCIPLES OF RATING SCALES:

IT RELATES TO LEARNING OBJECTIVE.

NEEDS TO BE CONFINED TO PERFORMANCE AREAS

THAT CAN BE OBSERVED.

CLEARLY DEFINES MODE OF BEHAVIOUR.

THE BEHAVIOUR SHOULD BE READILY OBSERVED

IN A NUMBER OF SITUATIONS.

ALLOW SOME SPACE IN THE RATING SCALE FOR

THE RATER TO GIVE SUPPLEMENTARY REMARKS.

3 TO 7 RATING POSITIONS MAY BE PROVIDED.

ALL RATERS SHOULD BE ORIENTED TO THE

SPECIFIC SCALE AS WELL AS THE PROCESS OF

RATING IN GENERAL.

CONT......

The Rater Should Be Unbiased And Trained.

Consider Evaluation Setting, Feedback And Student Participation.

Have Experts And Well Informed Raters.

Change The Ends Of Scale So That Good Is Not Always At The Top Or Bottom.

Assure That Rater Autonomy Will Be Maintained.

ADVANTAGES:• EASY TO ADMINISTER AND SCORE.

• ITS EASY TO MAKE AND LESS TIME CONSUMING.

• EASILY USED FOR LARGE GROUP.

• ALSO USED FOR QUANTITATIVE METHODS.

• MAY ALSO BE USED FOR ASSESSMENT OF INTEREST, ATTITUDE, PERSONAL CHARACTERISTICS.

• USED TO EVALUATE PERFORMANCE AND SKILLS.

DISADVANTAGES:

• DIFFICULT TO FIX UP RATING.

• CHANCES FOR SUBJECTIVE EVALUATION,

THUS THE SCALES MAY BECOME

UNSCIENTIFIC.

CHECKLIST

CONSTRUCTION OF CHECKLIST:

1. EXPRESS EACH ITEM IN CLEAR

,SIMPLE LANGUAGE.

2. AN INTENSIVE SURVEY IS MADE TO

DETERMINE THE TYPE OF

CHECKLIST TO BE MADE.

3. THE LIST OF ITEMS IN CHECKLIST

MAY BE CONTINOUS OR DIVIDE

INTO GROUPS OF RELATED ITEMS.

4. AVOID NEGATIVE STATEMENTS.

5. AVOID LIFTING STATEMENTS.

6. ENSURE EACH ITEM HAS CLEAR

RESPONSES:

YES OR NO, TRUE OR FALSE

7. REVIEW THE ITEM REPEATEDLY.

8. CHECLIST MUST HAVE THE

QUALITY OF COMPLETENESS AND

COMPREHENSIVENESS.

OBJECTIVE STRUCTURED CLINICAL/PRACTICAL EXAMINATION(OSCE)

HISTORY OF OSCE.....

OSCE Was Developed In Dundae, Scotland In The

Early 1970’s.

Introduced By Dr. Harden And Colleagues In 1975.

• OSCE is A form of performance based testing

used to measure candidates clinical competence.

During an OSCE, candidates are observed and

evaluated as they go through A series of station in

which they interview , examine and treat

standardised patients who present with some type

of medical problem.

CHARACTERISTICS OF OSCE

• It is an assessment approach primarily

used to measure clinical competence.

• Should be planned or structured

(predetermined clinical competences)

• Examination format or framework

• Different types of test method can be

incorporated into it.

OSCE (CONT...)

• In most stations students are observed

(by one or more examiners)

• Scored as they carry out the task or

interpret clinical materials (e.g.

laboratory data, X-rays), write notes

or answer question

OBJECTIVE(O):

• ‘O’ In the word stands for ‘objective and objectivity’ is a defining feature of this type of assessment.

• All candidates are assessed using exactly the same station, with same marking scheme. In an OSCE, candidates get marks for each step that they perform correctly, which therefore makes the assessment of clinical skills more objective rather than subjective which is where the examiners decide on whether or not the candidate fails based on the subjective assessment of their skills.

STRUCTURE (S):

• To achieve objectivity in the assessment of competency, a clinical skill or procedure is typically broken down into component parts in very structured way.

• Stations in OSCE have very specific task where simulated patients are used, detailed scripts are provided, a specific task is given to complete. Each skill of student will be examined by lecture ,and this skill is broken down into component parts and marking criteria is made in form of checklist.

CLINICAL(C):• CLINICAL EXAMINATION: The OSCE Is designed

to have both clinical and theoretical knowledge.

When theoretical is required only standardized

questions are asked. Sometimes when performing

clinical skill in practise setting, it is not unusual to be

interrupted by what else is happening. But clinical

skills are fundamental to nursing practise. therefore,

to overcome these issues simulation is commonly

used for OSCE in order to create an environment

similar to that of clinical setting.

• E.g.: A model of skin can be used to enable the

student demonstrate how to give IM Injection.

EXAMINATION(E):

• In OSCE, clinical competency is assessed by breaking it down to various components. In this way students are required to demonstrate not only ‘what they know’ but also they know ‘howto perform’ a clinical skill.
