You might have heard that somebody has obtained very good IQ score. Some may even show you their certificates to prove that they have got more than 120 IQ score. Higher the score, higher the intelligence level is presumed. However, such claims and assumptions are baseless, false and misleading. The highest IQ test score in one IQ test may not be equivalent to an average score of another test.
A good IQ score is a relative term. The initial score obtained by answering the items correctly is called a raw score. It is useless unless interpreted in meaningful terms by following the established norms. Even when two scores are processed through the psychometric principles, you can’t ignore the following important issues before determining a good IQ score:
Name of the IQ Test
Unfortunately, the psychologists have not succeeded yet to develop a perfect system of comparing two IQ scores got from different IQ test. Naïve comparison of two digits, however higher they may live skor be, can’t help you to determine a good IQ score. First of all you need to know on what IQ test on which the highest score was obtained.
Difficulty Level of the Items
The second problem to determine a good IQ scoring is the difficulty level of the test on which the claimed good IQ score was obtained. Your score will decline with the increasing difficulty level of the items being offered. It is possible that you get two different IQ score with two tests having same label. One reason for this variance would be the difficulty level of the items. The test developers vary the difficulty level of the test with the change of age, education and some other important factors.
You can find a number of tests with the same name but with different content. Even when you obtain 120 IQ score on an IQ test of verbal capabilities, you mayn’t claim the same level on another test of the same label containing mathematical items. General IQ tests try to develop items from all categories of intelligence but modern day testing industry is getting more specialized with every passing day. You need to consider content variation while determining any score a good IQ score.
