An important objective of many educational institutions is to prepare students for work. School officials need a "good" measure to know how effectively and efficiently their programs are meeting this objective. Three commonly used measures of measuring a school's performance are placement rates, the proportion of graduates in education-related jobs, and the internal rate of return. None of these three meet the criteria for a "good measure set out in this paper. Placement rates are too limited to be of any use. There are operational problems with the work-relatedness test but most importantly there is no consideration of costs. Rate of return is the best measure in concept but there are severe operational problems. A fourth measure, sometimes called the income-ratio, is suggested as an alternative. The ratio incorporates many of the good features of the usual measures and appears to provide the needed information and to meet the criteria of a "good" measure. (Author)
