This is the association subtest of the Netherlandic version of the Long Test For Genius, no longer in use. Currently only the English version of the Test For Genius (Revision 2004) is in use, to prevent candidates from comparing the different language versions to thus gain an advantage. Also, there was very little interest in the non-English versions.
The lack of interest is regrettable, since the problems of the Netherlandic verbal subtests, just as those of the nonverbal subtests, are of an exceptional quality. Some of them live on in the English TFG, and those that have no English versions are now revived in De Golfstroomtest.

Using the "split-half" method:
Item statistics are not published as that would help future candidates. To detect bad items, answers and comments from testees are studied, as well as, for each problem, the correlation with total score (validity of the item in this test) and the proportion of candidates getting it wrong (hardness of the item). Possible bad items are removed or revised, resulting in a revised version of the test.
