We discuss computerized essay testing, which has been rapidly replacing paper and pencil tests. A typical example is the national assessment of educational progress, NAEP. We present its writing assessment specifications and make comments on the background of why NAEP does not use automated scoring. We also discuss the automated essay scoring(AES)system, which is now widely used for some public tests, e.g., the Graduate Management Admission Test(GMAT)and the Medical College Admission Test(MCAT). Beyond the AES, an essay writing support system, Text Adaptor, which is developed by the Educational Testing Service(ETS), is described in detail. Currently, our interest is shifting to more sophisticated processing such as semantic and contextual evaluation of written essays, and the natural flow of paragraphs.
