Certified Legal Video Specialists (CLVS), videographers who have attended and passed a written exam that includes the requirements of Rule 30 of the Federal Rules of Civil Procedure, state and district court rules, and ethics, possess the professional knowledge, skill and equipment to videotape legal proceedings. They are required to demonstrate their proficiency by participating in a practical exam by recording a mock deposition. Only after passing both exams does the National Court Reporters Association award the videographer the designation of CLVS.
