Judicial retention is a way of re-electing judges without repeating the partisan competition and campaigning of a typical election. 
In Pennsylvania, judges are elected to the state courts for 10 year terms. When judges are elected to a state court for the first time, they run in partisan campaigns and may compete against other candidates. Then, when their 10-year terms are over, they are up for retention.  In a retention election:
- No other candidates are permitted to run for the seat.
 - The judge's political party is not listed.
 - Voters are asked a simple yes/no question: Should we keep this judge for another 10-year term, or not? 
 
This is meant to keep judges out of partisan politics as much as possible. It is very unusual for a judge to lose a retention vote.
