are meant to describe the full range of human abilities, rather than a representative sample. Is this exhaustive approach to be applied when developing descriptors for all of the occupational requirements?

THE Dictionary of occupational titles CONTENT MODEL The 1991 revision of the DOT contains descriptions of over 12,000 occupational titles, referred to as DOT codes. All information was obtained by trained occupational analysts who visited each work site, interviewed job incumbents, and observed them at work.

From page 24... ...
NET content model includes occupation-specific tasks as well as Detailed Work Activities (DWA) that are derived from multiple analyses of task information and are somewhat similar to the task descriptions similar to those included in the DOT.
|
From page 25... ...
The domains and occupational descriptors included in this content model were based on extensive research, reviews of current practice, and expert testimony. However, the advisory panel did not discuss in any detail why each domain was critical, nor did it outline the specific uses of each domain (Advisory Panel for the Dictionary of Occupational Titles, 1993)

NET prototype development project. Although the advisory panel criticized the DOT codes as being too job-specific, its content model included Occupation-Specific Knowledge, Occupation-Specific Skills, and Duties/Tasks Performed (Advisory Panel for the Dictionary of Occupational Titles, 1993)
|
From page 27... ...
The advisory panel expected that the prototype would then undergo additional development and revision before becoming the basis for the principal data collections. The prototype project team attempted to develop a content model that followed the advisory panel's recommendations, corrected the DOT's deficiencies, reflected new research and practice in occupational analysis, and incorporated the capability to adapt to a changing labor market and workforce.

NET prototype project are included in the current content model, it is important to examine their development and research base. The prototype project proceeded by constituting a separate development team for each of the content domains, reflecting the goal of providing multiple windows, or domains of information, to meet the needs of different users.

From page 29... ...
The Work Styles domain in O* NET is analogous to the Personal Qualities domain in the APDOT content model, which was to include information on an individual's characteristic, habitual, or typical manner of thinking, feeling, behaving, or responding as it relates to work (e.g., sociability, integrity)
|
From page 30... ...
NET content model is unchanged from the prototype content model. The prototype development team defined occupation-relevant Knowledge as a collection of discrete but interrelated facts and information about a particular domain having to do with performance in an occupation.

and to the preliminary findings of the National Occupational Information Coordinating Committee, which was attempting to develop a hierarchical taxonomy of educational preparation content. After many rounds of expert panel judgments concerning the comprehensiveness and suitability of alternative taxonomies, the prototype development team settled on a 2-level taxonomy consisting of 33 basic descriptors grouped into 10 more general categories.

From page 32... ...
Skills The current O* NET content model includes a taxonomy of Skills that is nearly identical to the Skills taxonomy in the prototype content model.

. Although we know of no evidence to support this statement, the project team used the sociotechnical systems framework to suggest that there are five categories of cross-functional skills (problem-solving skills, technical skills, social skills, systems skills, and resource management skills)

NET content model is nearly identical to the taxonomy in the prototype content model. The prototype development team carefully defined these descriptors of the basic characteristics of the work itself.

In the field test of the prototype content model, information related to many descriptors was obtained from a single manager representing the organization, and information related to other descriptors (e.g., autonomy, skill variety, leader behavior) was obtained by aggregating the perceptions of individual job incumbents.
|
From page 37... ...
DEvELOPMENT OF THE CuRRENT O* NET CONTENT MODEL Once the prototype content model was fully developed, the project team conducted a field test of the prototype questionnaires.
|
From page 38... ...
The second data set contained ratings by job incumbents, obtained through a survey of incumbents in a targeted set of 80 occupational units; the response rate to the survey was low, however. Despite the limited response to the job incumbent survey, the two data sets were adequate to support a preliminary evaluation of the prototype content model.

These changes are discussed below, and changes to the occupational classification system are discussed in Chapter 3. Organizational Context, Work values, and Occupational Interests Although the Organizational Context domain is a part of the current content model (see Figure 1-1)

Development of Tools and Technology Consistent with another advisory panel recommendation, the O* NET Center began in 2006 to develop another domain of more occupationally specific descriptors, known as Tools and Technologies or T2.
|
From page 41... ...
The 1991 DOT provided information on over 12,000 occupational titles, whereas O* NET provides information on 1,102 occupations.

From page 42... ...
The postprototype development of the DWAs and T2 information was in direct response to the proposed APDOT content model. One advisory panel recommendation that has not been implemented is the development of performance standards and critical performance outcomes for each occupation.
