Board Certified Lawyers go through an extensive application process to be even allowed to sit for a Board Certification Exam. There are a variety of requirements, including:
If an attorney passes through this gauntlet, they are allowed to sit for the Exam. That takes places once a year. The test is 5 hours long and consists of 3 long essay questions, and 100 multiple choice questions. The passage rate varies from 1/3rd to 1/2 most years.
Once an attorney is Board Certified, they must go through a re-certification process each 5 years. This requires a high level of ethical conduct and CLE attendance.
