A Texas school district is not teaching its students ASL but the Morphemic Sign System (MSS) system. This has many ASL users up in arms since the system isn't being used elsewhere. The Amarillo School District says it picked MSS because to promote literacy. KVII‑TV has a video report posted below. No captions, but you can read the text of the report here. (This post has been updated to reflect the difference between MMS and Exact Sign).
