ITEM2AbstractIt is important to keep in mind that tests are created to measure or verify certain skills andknowledge levels. Validity of the tests means that they measure what they were designed tomeasure. Reliability means that the measures from the test will always give the same or similarresults. Consistency is vital and one way to measure it is the test-retest method. Give the samegroup of individuals a test, wait a certain period of time and then give them the same test.Comparing the results show wither or not more knowledge and skills were acquired. The lengthof a test, according to item analysis, will not change these two significant factors. The length ofthe instruments is short ranging from 2 to 12 items.Keywords:item analysis, item theory, test-retest, reliability, validity
