ASL Stages of Development
is a 2-page list of skill development stages of children from 3 months through 5-6 years.

Guide to the ASL Development Observation Record
is a 12-page detailed observation that includes the 2-page list of stages.

These materials were developed by the Early Childhood Education program at the California School for the Deaf in Fremont to document the ASL language development of deaf children from the time they enter early intervention/early childhood to kindergarten.

The goal is to identify the language strengths and needs of each child and to document progress over time. It also serves as a criterion-referenced hierarchy to guide teacher in assessing their own role as language models and how they use language with children. Kudos to CSD for a wonderful assessment and planning resource!

developed by the Clerc Center at Gallaudet University. The ASL Content Standards help for planning and monitoring ASL development in children who are deaf or hard of hearing visual communicators.

A Good Start: Suggestions for Visual Conversations with Deaf and Hard of Hearing Babies and Toddlers
suggests research-based techniques for communicating with young children with hearing loss. Deaf children of Deaf mothers typically have age appropriate language levels at 18 months as compared to children with hearing loss who have hearing parents. This study considered what the Deaf parents are doing that results in these higher outcomes. Primary differences related to the
way that parents got the attention of their infant/toddler before communicating. These attention getting techniques can be of benefit to any family of a child with hearing loss, regardless of the communication option used.

Through Deaf Eyes
is an almost 2-hour video that portrays the history of deaf education and views of people who themselves are deaf. This video, or viewing portions with your students, may be valuable in Deaf culture studies and self-advocacy considerations.

It is the first of a series of three bilingual storybook apps, developed to help language acquisition and reading in all young children; in particular for those who are deaf and hard of hearing.
