DiCostanzo couldn’t pass tax board test

Former Mercer County Clerk Catherine DiCostanzo resigned this week from the Mercer County Tax Board, leaving her with just one paying government job instead of two. After narrowly losing re-election in 2004, she became the Mercer County Superintendent of Elections. But DiCostanzo didn’t resign because she opposed double-dipping; indeed, she left because after two years of trying, she has reportedly failed her certification test and required classes and the state would have mandated her dismissal after June 30.
