“…(see among others Borghans and De Grip, 2000;Clogg and Shockey, 1984;Freeman, 1976;Groot and Maasen van den Brink, 2000;Halaby, 1994;Hartog and Oosterbeek, 1988;Smith, 1986;Wolbers, De Graaf and Ultee, 2001).

Measuring and predicting overqualification from 1972-2010 : a secondary analysis of the pooled general social survey.

“…A well-known classification for occupations in the United States is the Dictionary of Occupational Titles (DOT). Utilizing the DOT is the most common method of measuring overeducation that originated with Eckhaus's (1964) and later Scoville's (1966) and Berg's (1970) utilization of the General Educational Development (GED) scale of the Dictionary of Occupational Titles to estimate the years of schooling required for average functional performance in an occupation in an objective way (Halaby 1994). …”

The GED scale estimates the mean years of required schooling in an occupation that is constructed by aggregating jobs, and because of this, it is ignoring the differences in the average years of required schooling across jobs within an occupation (Halaby 1994). Also, some have questioned whether the GED scale measures what it purports to measure (Halaby 1994).…”

Also, some have questioned whether the GED scale measures what it purports to measure (Halaby 1994). Though this may be the case, the JA method using the OED scale is still the most accepted measurement amongst sociologists for measuring overqualification (Eckaus 1964;Scoville 1966;Berg 1970;Burris 1983;Clogg and Shockey 1984;Halaby 1994;Livingstone 2004;Vaisey 2006).…”
