In the United States, anyone can run for judge. However, they need to meet certain qualifications to be eligible.
The qualifications vary from state to state but generally speaking, one needs to have a law degree and be licensed in the state in which they are running for judge.
Some states require that a person must be an attorney to run for judge. Other states allow any qualified adult citizen to run for judge, regardless of their profession or experience.
Generally, judges often have many years of experience in law before they become eligible for appointment and training as judges. This experience is necessary to be able to handle the heavy responsibility that comes with the position. Judges also need strong communication skills as they will often be required to speak in public, or give speeches at conferences.
