The primary qualifications for a job in captioning are a high school diploma or GED certificate and excellent communication skills. Employers prefer applicants who have call center experience, but this is not necessary for most roles. Performing the duties of a captioning job requires excellent short-term memory, fast and accurate typing skills, and the ability to communicate effectively through speech and text. Most captioning jobs are largely independent, so the ability to work well with minimal supervision is essential to success.
