What is Visual Communication Sign Language (VCSL)?

Visual Communication Sign Language (VCSL) is a research-based tool that evaluates the visual language development of Deaf and Hard of Hearing children acquiring ASL.
It tracks milestones in both expressive and receptive ASL to guide families and professionals in building language-rich environments.
​
This tool is not a test—it’s a conversation starter to support children’s language journeys.

Our DCS team is proud to be certified to administer a VCSL Assessment for Deaf and Hard of Hearing children aged 0–5. This allows us to track ASL development and provide meaningful family support.
