What is CART Captioning?
CART stands for Communication Access Realtime Translation. It provides spoken communication as text in real time, often for people who are deaf or hard of hearing. CART is a text-access service; it is distinct from American Sign Language interpreting.
A trained CART captioner uses reporting skills, a computer and realtime captioning software to produce text for a display. Captions can be shown on an individual computer or mobile device, or on a larger screen for an audience.
New professional opportunities for court reporters
CART can be provided in classrooms, meetings, conferences and other settings. For stenographic captioners considering NCRA’s CRC credential, the current route includes an online skills test and a written knowledge test. NCRA removed the separate Education component effective October 1, 2025; check its current test instructions before registering. NCRA CRC requirements. Remote CART requires a suitable audio connection so the captioner can hear the event and deliver the text.
Clear audio helps the captioner follow the speakers. A microphone or backup recorder supports the audio workflow; it does not by itself create professional realtime captions.
See the National Court Reporters Association’s explanation of CART and captioning for more information.

Common Questions and Answers
What does CART stand for?
CART means Communication Access Realtime Translation. It provides spoken communication as text in real time for settings such as classes, meetings and events.
Is CART the same as sign-language interpreting?
They are different services. CART delivers text; sign-language interpreting delivers communication in a signed language. Confirm the requested access service and display arrangements with the organizer and participant.
Does a microphone create CART captions by itself?
No. A microphone supplies sound. CART requires a captioning workflow with the appropriate professional skills, software and text delivery; buying a microphone does not establish the whole service.
What should I test for remote CART?
Check the audio feed reaching the captioner, the communication connection and the text display participants will use. Test actual speaker positions and remote participants before the session begins.
