 Since we have been talking about the competence of test user and the certifications which they can get, but there are some very important issues in assessment which we are going to be looking into it now. The first important thing is test construction. Since we use frequently different type of test which are being developed by international affiliates and we adapt them either or we translate them either and use them in local setting but there are some situations where we are stuck with those tests and we find that they are culturally loaded and there are so many other barriers involved into it and we have to develop the test. So psychologists who develop test and other assessment techniques use appropriate psychometric procedures. It is not that we generally collect questions and randomly apply them to our sample and we will get a test or a survey. There are different psychometric procedures which are involved into test construction. Current scientific or professional knowledge is used for test design, standardization, type of validations, reduction or elimination of biases and recommendations for use. So we need to see what item is statistically going to be deleted from the list of questionnaires by using reliability analysis and it is very specific component, item if alpha deleted and then we have to see which items factor loading is good enough to keep that into the test. What factor loadings in social sciences we are going to look for? The ideal one is probably 0.60 but if we cannot achieve to that way we have to see according to the test construct it would be 0.35 or 0.40. So you know there are lot of psychometric analysis involved in making a test. It is not that a simple thing we just randomly collect the items and we go to population to apply that questions on to them. Interpreting assessment result, while interpreting assessment results, psychologists take into account the purpose of assessment because it is very important as well as the other test factors and the individual characteristics of the person who is performing into the test and who is being assessed such as the situational factors may affect the person then the personal factors may assess the person and then the linguistics have its impact on the test and the cultural differences can create a impact on the test users. So Jaga, work, mahal, its internal instinctive motivation and lot of cultural differences who can impact the test. So it is very important that while interpreting the assessment result one have to take into account all these factors. So here it is very important to talk about that what if the assessment is being done by an unqualified person who is not aware of the fact that all these things matter a lot. So psychologists do not promote the use of psychological assessment technique by unqualified persons except where the test is being conducted for training purposes with appropriate supervision. So it is not so easy that anyone could come in, walk in and apply a test and interpret the result. We need a specialized person who has some degree in assessment and psychometrics or who can interpret the test properly. Now what if the test is an obsolete test and it is an outdated test, definitely it is going to produce obsolete and outdated results. Psychologists do not base their assessment or intervention, decisions, recommendation, reports that are results on the basis of those tests who are being outdated for the current purpose and obsolete and not useful for the current purpose. Now you may be thinking that how can a test become an obsolete test. Here I would like to give you one example of Waze Intelligence Test. When we talk about Bessler Adult Intelligence Test and Waze Wessler Intelligence Test for children, we know that when these tests were made, the criteria and age range of the test were initially for an 8-year-old child to be able to solve a 2.5-year-old child, because of world being a global village, because of the proper dissemination of information. So that age range was reduced to 5-4, 3.5 and recently that 2.5-year-old child also has that knowledge which he probably had for 9 years. So this is how the world has changed, the knowledge transformation has changed and in result to that certain tests has become obsolete. And now we cannot interpret them as we did many years ago. So probably because of different change, because of the cultural advancement and information about the other parts of the world, things have become changed now and many tests have been obsolete and now we cannot use them anymore and on the basis of those tests, we need to keep going on revising those tests or poodi duniya mein teston ki revised version isi liye aate hain. But in any case, if we are not available with the revised version, it is very unethical to use the older version and yet claim that this is the result of any specific test which is being internationally recognized.
