Dear Vandanaa, any psychometric test, whether paid or otherwise, has to be reliable and valid. The accuracy of the results is of utmost importance. While you may use the free versions, the results may not be accurate, and using inaccurate results could do more harm than good.
Issues with Psychometric Tests
The second issue with psychometric tests is the variation in results. Suppose you hire two companies that measure leadership competency. Imagine you use their paid versions. Nevertheless, what is the guarantee that even though the tests are different, their results will be the same? If there is variation in the results, which one is correct?
Suppose you repeat the paid test a year later. What if the results vary after a year? Then, which one will be correct, the recent one or the results declared a year ago?
Assessing Personality with the Carl Jung Personality Theory
Yes, it is difficult to use the paid versions each time. However, when I discuss the "Carl Jung Personality Theory" in my training programs, I teach my participants how to assess personality by asking the right questions. However, asking the right questions is not easy; it requires immense maturity. This maturity comes with guidance. Assessing whether the replies are correct or not requires an even more mature mind. Do you have such mature staff in your company?
Thanks,
