ASL University is an online curriculum resource for American Sign Language students, instructors, interpreters, and parents of deaf children. Feel free to use the various lessons and resources for self-study. There is no need to register or pay (unless you want documentation to fulfill high school, college, or continuing education course requirements). If you are a teacher, I give you permission to use the lessons to teach your in-person classes. Enjoy! -- Dr. Bill Vicars

ASLPro.com was created to be a free resource for the classroom teacher. Teachers can create accounts and personalize a quiz for their students' use, then take them into a lab and let them practice seeing models other than their own teacher. Because our signs are designed to be used in student quizzes, Non-Manual Signals are purposefully omitted.
We welcome the general public to view our site, but it should be noted that this site is not designed to be a stand alone learning tool. A user's best course of action is to enroll in an ASL class with a qualified teacher who can guide them in such variations as regional differences and facial expressions that are not addressed in our video database.

A Basic Dictionary of ASL Terms
Here are a few American Sign Language terms to help those of you who are trying to communicate with a person who signs, but does not hear. New word definitions are being added, and this will soon bring the total number of ASL terms to more than 1270! Also included is the basic alphabet and numbers 1-10.
This dictionary has both animated and text definitions. The text definitions also have letter or number sign images to aid in visualizing the sign. This will allow you to quickly locate a word, read how to sign the word, and choose to view the animated sign if you wish.
The sign images are displayed from the perspective of the viewer, not the signer. It is easy to remember this if you imagine that someone is signing to you while you are viewing the word definitions.
In Sign Language, facial expression including the raising or lowering of the eyebrows while signing, and body language are integral parts of communicating. These actions help give meaning to what is being signed, much like vocal tones and inflections give meaning to spoken words.
