Only persons who have had the benefit of a fairly complete elementary school education will succeed very emphatically in this test of ability to write a composition in the English language. The test may be given to large numbers of people at the same time just as readily as to a single individual. The result of the test is, however, a very good index of the general intellectual capacity of the individual, unless he is handicapped by lack of familiarity with the language. The most common use which most of us have for ability at composing in English is in writing letters to our friends or to those with whom our business brings us into contact. For this reason, the test consists in the statement of a condition under which any one of us might find ourselves and in asking the candidates to write an appropriate letter. The result is graded into one of five groups, according to its general quality. The problem presented to the candidate is fairly complex. First of all, he must be able to understand the situation described by the examiner and to appreciate what type of letter would be most appropriate under these circumstances. He must also be able to write the words which would express his feelings in the described situation, and in order to make his feelings clearly understood he should be able to punctuate and organize his sentences effectively. The result is a useful index of the general efficiency and maturity of any candidate who has been taught to write in English. In industrial life there are many types of positions for which persons whose ability to compose written English need not be better than “Inferior,” although there are other positions which would require “High Average” quality of English composition. The advantage of the following Mentimeter lies in the possibility it gives of identifying more exactly just what quality is meant when one speaks of “High Average” composing ability. In the public schools the Mentimeter will serve as a crude basis for classifying the general quality of the compositions written, but for highly scientific work it would be desirable to secure some form of the “Hillegas Scale” which is much more exact and well standardized. A very entertaining evening could be enjoyed by giving this test to a group of people gathered together for social purposes, especially with a group which had tired of the ordinary means of entertainment. Reading the products written should in such a case be entrusted to some one or two individuals of good reading ability and wise judgment. Frequently the results would contain very amusing paragraphs. _Directions for Giving the Test._
