What is Indian Sign Language?
Indian Sign Language (ISL) is the visual language used by many deaf people in India, with its own vocabulary and grammar using handshapes, movement and facial expression. It is not signed Hindi or English. The Indian Sign Language Research and Training Centre (ISLRTC) develops ISL resources and dictionaries, and NEP 2020 recommends standardising ISL and developing learning materials in it.
What this means in practice
For deaf children, early access to a full language, whether signed or spoken, is crucial for learning and wellbeing. Teachers and families who learn ISL help deaf children participate fully.
ISL in education
- Some schools for deaf children teach through ISL.
- Interpreters can support deaf students in mainstream settings.
- ISLRTC publishes dictionaries and learning resources.
- Teachers and classmates can learn basic signs for daily communication.
Getting started
Learn greetings, names, classroom instructions and feelings first, and practise with deaf signers where possible.
Supporting deaf learners in mainstream schools
Deaf learners in mainstream classes may use ISL, spoken language with hearing aids or cochlear implants, or both. Ask the family about the child's language and communication preferences. Provide visual supports, captions and written instructions. Where the child uses ISL, an interpreter or signing staff member makes lessons accessible. Contact with deaf adults and other deaf children supports identity and wellbeing, so families may value links with local deaf associations.
Practical next steps
- Learn basic ISL signs.
- Use visual supports alongside signing.
- Involve deaf adults and the child's family.
- Explore courses from recognised providers.
What to keep in mind
Basic signs are a start; formal teaching through ISL requires fluent signers and trained teachers.
Common follow-up questions
Is ISL the same across India?
There are regional variations, which ISLRTC's work aims to document and standardise.
Can hearing children learn ISL?
Yes, and it helps them include deaf classmates.
