This document provides an overview of psychometric testing, which are standardized tests designed by psychologists to measure traits like cognitive abilities, personality, and behavior. Psychometric tests are commonly used in recruitment and selection to identify the best candidates for roles. They can also be used for training and development purposes. Common types of psychometric tests include personality tests, ability tests, and interest tests. Popular assessment tools mentioned include the Myers Briggs Type Indicator, 16 Personality Factors, and DiSC. While psychometric tests provide objective insights, they also have limitations like not guaranteeing on-the-job success and require trained administration and interpretation.
