Perhaps I am the only TVI who forgets a little Nemeth from time to time….but fortunately, there is a quick and easy Nemeth tutorial at APH to help me out! This tutorial includes examples that are screen reader friendly, so our students can also be taught to use it. I have several hardcopy Nemeth resources, but this website is free and available on the go, making it a handy go-to reference in any situation. What’s more, it includes practice exercises, so it can be used not only as a reference, but as a refresher or tutorial. The indexing and organization of the website make it very easy to quickly find what you need: APH Nemeth Website
