Hydrologic Technicians
Every task in this role, whether it passes the census's structural hand-over screen, which models pass it, and why. It is a screen, not a claim about what AI can do: a task can pass and still be beyond the systems of the day. The stricter and looser rules re-vote every task, and small differences between roles are noise.
Passes the screen · 2 of 16 tasks
Locate and deliver information or data as requested by customers, such as contractors, government entities, and members of the public.
