ecause we do not like the criteria is confusing the issue. Hoffmann’s<br />

concern rfth ambiguity is relevant only when the content vaLidity of a<br />

test is the primary constd.eratFon. Eve,1 80, tke customary item acreesing<br />

and selection in the constructicn of teats insurea a reaeonably satiafactory<br />

degree of content valfdity. This io particularly true in the<br />

case of our military tests which are designed to cover specific job areas.<br />

What about Hoffa%M'S cLaim that the “deep” examinee fs penalized<br />

by multipLe-choice iteM? What he seems to be saying is that the very<br />

dull examinee will fail the itea more frequently than the superficially<br />

bright examinee, but that the exceptLonally bright examinec vi11 have<br />

more trouble with the same item than the superficially bright examinee,<br />

Naturally, the brightest examinees are more apt to discover ambiguities<br />

than are other students. But Hoffmann’s ideas about the consequences of<br />

their perceptiveness do not hold up.<br />

To get back to Hoffmann’s assumptions, he states that tests,“... take<br />

account of only the choice of answer and not of quality of thought that<br />

lead to the choice,” and “They neglect skill and dtsciplfned expression.”<br />

This attribute he catls “quality of thought I’ is not defined, nor is any<br />

reliable and valid way of measuring it suggested. One mfght assume that<br />

Hoffmann would advocate use of the essay examination as a measure of his<br />

quality of thought. Such is not the case, for he outlines no less than<br />

four very convincing arguments why the essay test should not be used for<br />

that purpose. (L. Difficult to choose a topic fair to a% 2. difficult<br />

to determine whether the essay is actually revelant to the question; 3.<br />

difficult to overcome the problem of negatfvc halo due to poor handwriting,<br />

spelling, etc. ; 4. difficulty to maintain consistency within and between<br />

scores.) I often hear this quality of thought argument twisted around to<br />

say that just because a man scores high on the test does not necessarily<br />

mean that he can do the job. Most generaLly, those advancing this<br />

argument mean that the man will not do the job. While it may be true that<br />

a high score on an achievement or’ job knowledge type test does not<br />

automatically indicate a high degree of motivstion, it is eqtially true<br />

that the Low scorer cannot perform the fob, that is, he does not have<br />

the knowledge to perform regardless of hie motivation. Of course this<br />

depends on test validity and test purpose. It is up to us to define<br />

the purposes to which oar instruments may be put and to determine the<br />

validity, for various purposea, of these instruments.<br />

At this point we might conclude that Hoffmann does not like any kind<br />

of testing. We would probably be correct. He criticizes objective tests;<br />

yet he leaves no alternatives for mensurement. When he argues that &he<br />

results of an educational testing service st*)qy showing an essay teat<br />

was less good than an objective examinstion are silly and could not<br />

possibly have been obtained, he is simply confusing content with predfctive<br />

or concurrent validity.<br />
