As parents who are raising a child that doesn't fit into the "box," in terms of learning styles, we know how painful and difficult it can be. At Lexis the small setting and individualized teaching plans that are made for each child make a huge difference in their ability to learn, feel encouraged and feel empowered to take control of their own learning. Lexis is a school that looks at the whole child and encourages them to learn to their fullest potential—challenging and encouraging them every step of the way.
