This paper reviews a major debate that has implications for educational research and policy communities. The debate concerns the skill upgrading versus downgrading of occupations in the United States and relationships to schooling and vocational preparation. The review summarizes the major positions in the debate, surveys the evidence on skill changes, including methodological and design issues and concepts and measures for skill, and discusses research and policy implications for general and vocational education.sures of skill are uneven. Unidimensional, undefined concepts along with nonmeasures and indirect measures are the norm; multidimensional concepts and direct measures of skill are the exception. Current evidence suggests we give more attention to two primary dimensions of the skill requirements of occupations: substantive complexity and autonomy-control. We do not have comprehensive knowledge about the relationships among these dimensions of skill requirements of occupations, the capacities of workers, and the learning and skills acquired through education.More comprehensive and accurate judgments about skill changes will require attention to design and methodological issues. Skill changes occur at the levels of occupations, industries, firms, sectors, and the society. Aggregate and case studies comprise the major designs in the study of skill changes. The designs have characteristic strengths and weaknesses and tend to yield different conclusions. Comprehensive understanding will require both types of designs along with consideration of shifts in skill through changes in the work content of occupations and through compositional shifts in the occupational structure. Further, existing studies afford only limited coverage to the sample space of work and jobs in the economy for limited spans of recent history.The following sections of the paper sketch the major positions in the debate, review the state of the evidence, and finally, consider the issues and implications for educational policy.
Theoretical Positions 1
Upgrading ArgumentsThe industrialization thesis best illustrates the upgrading position (Kerr, Dunlop, Harbison, & Myers, 1964). The logic of industrialization involves a division of labor that evolves along the lines of greater differentiation and efficiency. Technological change raises productivity, requiring a broader variety of skills and higher average skills from the work force. Industrialization requires greater occupational and geographic mobility and an educational system that supplies the skills, training, and specialization for the economy. Automation and other technological changes tend to eliminate boring and routinized work; workers experience less close supervision and have more responsibility; work becomes more complex and interrelated, particularly in high technology fields.Proponents of the upgrading thesis cite two forms of evidence: (a) major shifts in the occupational structure, particularly the growth of professional, technical, and managerial occupations since 1900; and (b)...
