[Excerpt] Educational and political leaders are calling for improvements in the signalling and certification of academic and occupational skills to the labor market. The Secretary's Commission on Achieving Necessary Skills (SCANS), for example, has recommended a national system for assessing individual accomplishments and work readiness that would be "designed so that, when teachers teach and students study, both are engaged in authentic practice of valued competencies." For educational reformers, better signalling is not an end in itself but a means of inducing students, parents, teachers and school boards to place greater priority on learning and of reforming the content and character of secondary education.
