The test consists of a series of sentences in each of which certain words have been omitted. Dotted lines appear at those places where words are missing. The persons being examined are asked to write on the dotted lines the words which have been left out. The blanks left in the sentences are all of the same length in order not to suggest the word to be used. The Mentimeter form of the test contains 20 sentences, graduated in difficulty, from very simple sentences which the average second-grade public school pupil can complete easily, to very difficult sentences which the average college student will be unable to complete satisfactorily within the time limit. The ease with which one can understand what is to be done in this test makes it particularly useful with children in the elementary schools, and with adults of little education, as a measure of language ability and general intellectual capacity in the manipulation of ideas and words. Although it has been used by many teachers and supervisors as a test of reading ability, it should probably be classified rather as an intelligence test than as an educational measuring instrument. Teachers do not and should not give direct instruction in the art of writing missing words, for almost no situation will arise in practical life where this sort of skill would be necessary. It is very difficult to determine just what mental powers are tested by the sentence completion test. Quite certainly the result obtained is a complex effect. The person who is successful in this test must first of all be able to read and understand the words which are actually present in any sentence; he must have certain habits of associating other words not present with those which do appear; from all of the words which come to his mind as associates of the printed words, he must choose those which fit most aptly the thought expressed; and from those words which would fit into the thought of the sentence he must use good judgment in selecting and writing the one which makes the smoothest and best sentence. Lack of mental ability or of familiarity with the English language will result in a poor showing at almost any step of the process and in a low score in the test as a whole.
