The standardization of CareerGuide's Psychometric test is on sound footing on Pilot Study, Item Analysis, Norms, and Reliability and Validity scores. All the assessments has been designed precisely and carefully keeping in mind all the above mentioned factors.

Item Analysis:

After ensuring the conceptual clarity, items were constructed with the help of 5 experts for Aptitude and Interest that is required to study the various streams/careers/subjects. Each item in the test was carefully picked with the agreement of all the experts

Norms:

In terms of testing, norms can be described as the average scores among an identified group of people. Such norms provide a basis at which test scores of individuals can be compared.. In order to establish norms, tests are administered to a large population that is selected carefully in order to represent the proper population that is intended to be served. Age norms and grade norms are type of norm established.

Reliability:

Reliability of the assessment is measured to see the consistency of scores in different assessments of the same test or of different forms of the test on the same person or in the same test. Test Retest method of reliability has been used on all assessments of CareerGuide.

Another method of Reliability used was

Inter Rater Reliability

This type of reliability is assessed by having two or more independent judges score the test. The scores are then compared to determine the consistency of the rater's estimates.

Validity:

Validity is the extent to which a test measures what it claims to measure. It is vital for a test to be valid in order for the results to be accurately applied and interpreted. Validity isn't determined by a single statistic, but by a body of research that demonstrates the relationship between the test and the behavior it is intended to measure.

The validity of the test was calculated by the following methods:

Content validity

for the test was calculated. Content validity (also known as logical validity) refers to the extent to which a measure represents all facets of a given social construct. It is essentially a method for gauging agreement among raters or judges regarding how essential a particular item is.

Validity of scores by comparing the conventional counseling method and the assessment method:

The procedure is defined as follows: Ask the career counselors to counsel the student and decide a stream preference for the student by adopting a counseling procedure that they normally use. Ask the same student to take the Assessment. Compare both of them i.e. the stream/career/branch preferences given by the counselor and the ones that are came out in the assessment Report. If both are same then it could be said that the method adopted for the test is correct and appropriate. If the results are not the same they must be checked to see where the error occurred.
