Is this level of responsibility normal for a staff?

By | July 20, 2017
I currently am a staff in an IT audit position.

I feel sometimes like I am acting staff, senior, and manager on my engagements, with responsibilities including:

Coordinating directly with upper Audit management.

Identifying and recommending scope changes.
Coordinating documentation requests and meetings with the client.
Documenting evidence provided by the client.
Managing the budget.

Is this typical?
