There is no one way to prove that a company has a "glass ceiling" for women or for anybody else for that matter; each case has to be viewed on its own facts. 

But it is possible to get guidance from other cases and situations.  See the court's decision in Conti v. American Axle and Robert Abell's discussion at Sex Discrimination and the Glass Ceiling.

If you have suffered sex discrimination or discrimination because of a glass ceiling, contact Lexington, Kentucky discrimination lawyer Robert Abell at 859-254-7076.
