POV Check 

 is used, as the tag itself says, to get the community to check the article for neutrality. This means to try and get an uninvolved set of eyes to check the article. It is a process similar to a GA or assesment review, but focusing on POV concenrs. It should not be removed until such process are done. It doesn't mean that going through a POV check resolves POV issues, but it is usually a good start.
