So THAT'S what that means. #5
Raise the bar
"Raise the bar" is to raise the standards that need to be met.
This might be an easy one but maybe someone will find it useful.
In track and field, the high jump and pole vault have a horizontal bar that jumpers are required to jump over. The bar starts off low and is raised each time the jumpers successfully make it over. This continues until only 1 jumper remains.
