	abstract = "This study examined the feasibility of employing Project Essay Grade (PEG) software to evaluate web-based student essays that serve as placement tests at a large Mid-Western university. The results of two experiments are reported. In the first experiment, the essays of 1293 high school and college students were used to create a statistical model for the PEG software. PEG identified 30 proxes (observed variables) that could be incorporated into an evaluation of the written work. In the second experiment, the ratings from a separate sample of 617 essays were used to compare the ratings of six human judges against those generated by the computer. The inter-judge correlation of the human raters was <I>r</I> = 0.62 and was <I>r</I> = 0.71 for the computer. Finally, the PEG software was an efficient means for grading the essays with a capacity for approximately three documents graded every second. Cycle time from the websubmission of the document to producing a report score was about 2 minutes. Although PEG would appear to be a cost-effective means of grading written work of this type, several cautionary notes are included.",
