What is the purpose of assessment in the human service field?

The same as assessment in any task. When I was in charge of planning and management of ship modernizations and overhauls, the first task was to inspect the ship with trained personnel to make a list of work, with descriptions, and cost estimates to do the work. Then with that assessment in hand, one could plan (and budget) the work.

Then with an agreed work package, we looked in more detail at what material, how long it took to get it, and then how long the work would take, with impacts on other work approved. When this assessment was complete, we made a work schedule and managed to that schedule.

So what was the purpose of assessment: It was an analysis to give data to the decision making process, and provide a standard to compare the final product to. All this is by nature the essence of project engineering and management.

Now you tell me what is the purpose of assessment in the human service field? We will be happy to critique your thinking.
