This site is designed to make it easy for a student to take daily spelling tests, and as they become proficient with one set of words help them continue to progress. It also allows parents and teachers to easily see their students progress so that they can be involved in any way necessary.
In order to begin, a parent or teacher needs to sign in. They can then set up accounts for as many students or children as they want.
Give the site a try, I hope it works well for you.
