'polling'?

Hi,

I'm translating a book on leadership in the time of economic uncertainty, and they said at the early stages of the current downturn, DuPont had a communication programme in which managers explained to all employees the origin of the downturn and what the company needed to do, and they also asked each employee to identify 3 things he/she can do to help conserve cash. After that communication programme the company conducted polling to see how well the employees understood the nature of the crisis.

=> My question is: usually 'polling' is understood as 'voting for something/somebody', but does it mean so in this case? I think if that company wanted to know how much their employees got what they wanted to convey, they should do some kind of research, not voting.

What do you think?

Many thanks,

Nessie.
