shift the goalposts

Move success criteria

To shift the goalposts is to change the criteria for success or the rules of an argument after someone has already met the original standard.

The image comes from sports—moving the goal would invalidate a legitimate score.

Every time I meet her expectations, she shifts the goalposts.

The tactic frustrates honest engagement by making agreement or achievement perpetually out of reach.
