Words are placed into Categories, and the program gives you the ability to study and hear by those categories. Sub-categories like the ones that are under Nature, provide the ability to segment the words into a more learnable format.

This helps to make the program easily understood by beginning students, while advanced students can not only utilize this function but can access more complex features.

The scalability of T.R.A.I.L.S. allows System Administrators to control all access to the program. Student, Teacher, and even Administrator levels are fully controllable and require no reprogramming. As students or users advance, they can be placed at a higher level of access by a designated Teacher or Administrator.
