Since traditional psychometric methods for reliability can not be used to calculate specific parts in a test, we use so called "New Quality Analysis" (simlilar to the methods used by Dr. Ivan Ivec) to be able to determine the quality of a the intervals listed below. A New Quality figure is about 1015% lower than the corresponding Cronbach's Alpha.
For instance the TERO41 test has a New Quality level at 0.89 over IQ 160, This would correspond to a Cronbach's Alpha very close to 1.0 which is as good as you can get. But even levels from about 0.6 are fully acceptable.
To measure the "Real IQ" for people with a personal portal at this site, we currently use a method to calculate the mean of rarity for all tests, this includes a method to compensate for low and failed scores.
