Dear All,
I saw a whole lot of requests for the Testing & Assessments guide [Employer's Good Practice Guide]. Thus attached is the document for your perusal.
Hope it is useful to you'll. Chapters 3 -9 is what you might find relevant. Please note that is document has not been updated for a long time...but will give adequate information to people who want to know more about Psychometric Testing & instruments.
Keep sharing,

Hi Sree,

Thank you for your question.

Regarding psychometric tests, they are generally considered reliable measures of various psychological traits. However, it is essential to note that the reliability of these tests can vary depending on factors such as the test's quality, administration, and scoring procedures.

As for getting different results from the same subject in two consecutive days, it is possible due to several reasons. Factors like the individual's mood, fatigue, or external influences can impact test results, leading to variations even when the same test is taken on different days.

In conclusion, while psychometric tests are designed to be reliable measures, it is essential to consider various factors that can influence test results, including the potential for variability when administering tests on consecutive days.

Best regards,
Noor

Hi Sree,

Good standardized psychometric instruments have a reliability ranging between 0.60 and 0.87, which is good. A good instrument should produce the same or similar results/scores on consecutive trials, with all other conditions remaining the same or constant. If you are getting different results on consecutive trials with all conditions remaining constant, then the instrument fails the test of reliability. However, before you go around judging the instrument, make sure all extraneous variables are under control. It should also be kept in mind that you are dealing with human beings, and our behavior is constantly changing and adapting to the environment, so there will be no instrument that will give you 100 percent accuracy.

Namaskar,

Let me add to Noor's comments. Certain aspects of human behavior are consistent, while others are inconsistent. Psychological testing deals with the consistent aspect. One of the reliability measures is called test-retest reliability. This estimation answers whether the scores across time are consistent. For standardization purposes, normally a gap of two months is given, and a correlation between the two sets of scores is expected to be around +0.90. The level of consistency considered acceptable may vary depending on the author or project director.

Gerontology shows that consistency pervades throughout life.

Thank you for the attachment. I was actually looking for one to start this test in my company, and this is very useful to have a basic idea to start the procedure.
