A Field of Application (FOA) is a technical domain or specialty. FOAs are what tailor an assessment to the work someone actually does — they decide which specialized skills get included.
A Standard Job gives an assessment its core skills — the foundation expected of anyone in that job.
A Field of Application (FOA) adds technical specialized skills on top — the deeper expertise tied to a specific area of work.
For example, two people may share the same Standard Job but work in different FOAs, so their specialized skills differ.

When a manager builds an assessment, they:
Pick the Standard Job → this brings in the core skills.
Pick one or more Fields of Application → each one adds its set of specialized skills, grouped together so they're easy to review.
The result is a skill list that reflects both the job and the specialty.

In the skill list — skills added by your Fields of Application appear together under the "Technical Specialized" group (the progress panel shows it as Technical Specialized (FOA), with each FoA as a sub-group). This is where the FoA's effect is visible on the page.
Employees see the FOAs chosen for them when they review their setup, and the specialized skills appear in their self-assessment.
Managers choose FOAs while creating an assessment.
