new battery has a broader coveraKe than the old oXe. The two primary
changes arc that we expanded the number of subtesty in the academic or general
ability domain,

and that we included more tests of interests and attitudes
I
or mca~urcs of the willingness factor. We retained the old standbys of
Arithmetic Reasoning and Word Knowledge, and we .Idded’ measures of, Scikce

Knowledge and ?fathematics Knowledge to provide more precise measurement in
this +ri:ical area of general mental ability. By including these additional
tests, we obtained more accurate prediction of success in the different job
arcas. (Chart 1)
The other major improvement is that WC added nore interest measures. The

The intcrcst ncasures add to the prcdicti!n cf success in relevant job

training, in addition to the measures of general ability and specific measures
of infomtion in a field, such as electronics information and automotive

Th? information tests also tap a willingness factor. They cover
matcrfal that most anyone with an interest and aptitude in th,c area can
pick up. Electronics and automobiles are common to our culture, and a
young persca can readily bccoae expert in these areas if he has the initin-
