Psychological tests have five key characteristics: 1) Standardization ensures uniform testing conditions, 2) Objectivity means scoring is free of bias, 3) Test norms establish a frame of reference to compare performances, 4) Reliability means a test yields consistent measurements, and 5) Validity refers to a test accurately measuring what it is intended to measure. These characteristics help ensure psychological tests provide useful and meaningful data about individuals.

Characteristics of
Psychological Tests

3. 1. Standardization
It refers to the consistency or
uniformity of the conditions and
procedure for administering a test. To
achieve standardization, people must
be tested under uniform conditions.

4. 2. Objectivity
It refers primarily to the scoring of the
test result. The scoring process must be
free of subjective judgment or bias on
the part of the scores.

5. 3. Test Norms
To interpret the result of a psychological
test, a frame of reference or point of
comparison must be established, so that
the performance of one person can be
compared with the performance of others.
This is accomplished by means of test
norms.

6. 4. Reliability
It refer to the consistency of a person’s
score. For example, a boy takes a
cognitive score. For example a boy takes a
cognitive ability test and achieve a mean
score of 100 and after one week if we
repeat the test and he achieve a mean
score of 72, we would describe the test as
unreliable because it yields inconsistent
measurements.

7. 5. Validity
It refers to the test’s accuracy in
measuring, what it is supposed to
measure. For example, people’s scores
on that test should be strongly correlated
with their grades in school.
