Two similar clusters of position descriptions (National Office and Regional Office) now cover most lines of work at most grades. Where employees perform at more than one grade level in a particular line of work, the probable levels in which employees will function have been addressed (for a few specialized, one-of-a-kind jobs and/or occupations with very small populations, building functional position descriptions was not cost-effective). Subject matter experts from the various occupations afforded a validation phase to the process.

In recognition of the shifting focus and one-stop, customer service emphasis of the Workforce Investment Act, three core ETA occupations have been joined in a single multi-disciplinary position description at the journey or full performance level (GS-12). The differentiation is identified under part IV. UNIQUE POSITION RESPONSIBILITIES where the supervisor's check by the appropriate paragraph will determine the title and series: Unemployment Insurance Program Specialist, GS-0106; Manpower Development Specialist, GS-0142; or Apprenticeship and Training Representative, GS-0243. This trend is followed in the National Office for experts and team leaders in those lines of work and for team leaders in Regional Offices (Regional Office multi-disciplinary expert position descriptions at the GS-13 level apply only to Unemployment Insurance Program Specialists and Manpower Development Specialists).

In a design similar to the multi-disciplinary position descriptions, a single position description for each grade level covers virtually all Management Analysts, Program Analysts, and Management and Program Analysts at that grade. As with the multi-disciplinary position description, the supervisor indicates the primary focus (and thereby the position title) by checking the appropriate paragraph under part IV. UNIQUE POSITION RESPONSIBILITIES.
