Learning sign language is like learning any other language. You have to study it and then use it if you are to be proficient. Most people who learn sign language will lose it because it isn't something that they use very often. The best advice I can give is to learn the manual alphabet and a few essential signs. That way, you can always spell out the words with the manual alphabet whenever you don't know or remember the sign.

They are the quintessential component that insures that the hearing conservation program is effective and provides the needed assistance to the child and family. My experience is that hearing conservation programs generally do a great job in identifying hearing loss. Where the programs typically fail is in the follow up. This is where the school nurse can really make the difference. If there are any questions, the nurse can contact an audiologist to help with for effective follow up and care.
