Four year-old Mara was excited about going to preschool. She loved to play with other children and listen to stories, but her teachers and parents noticed that she didn't speak as well as the other children. Mara usually pointed and grunted to let others know what she wanted. In a meeting with Mara's parents, her preschool teacher suggested that the preschool special education team evaluate Mara. Shortly after this, Mara's parents got a letter asking them to agree to the evaluation.
