The word ‘psychometric’ refers to the measurement of the mind and is a short version of “psychological measurement”. Psychometric tests are a standard and scientific method for the legitimate and logical measure of individuals’ mental capabilities and behavioural style. Psychometric tests are designed to measure the behavioural traits and mental capabilities of the person. These tests are used for the assessment of two core skills: personality and ability and further to identify the hidden behavioural aspects of the candidate.
What are the Psychometric Properties?
During the developing of the students, choosing the correct set of assessments is the pivotal decision that can make or break the success of an individual. Hence, familiarising them with these tests will help in a superior, quicker and precise decision-making.
Two critical properties of an individuals’ assessment, from a psychometric view are its reliability and validity.
Reliability of a Psychometric Test
The reliability of a psychometric test refers to the consistency of scores obtained by the students under their repeated testing on the same test under identical conditions.
Since the ideal condition is impossible to meet, one aspires to collect evidence of reliability and express it in the form of a correlation coefficient that can range from .00 to 1.00. A perfectly reliable test would have a reliability coefficient (Cronbach’s alpha) of 1.00, and a completely unreliable test would have a reliability coefficient of .00.
