Each person has a particular rate of growth and development. The area of literacy (the process of learning to read and write) does not escape this determination. Each child has their own learning speed and this can vary even more in bilingual children.
Detecting the difficulties that an individual may present in this area early and effectively through an early evaluation can represent a significant improvement for the well-being of the person. For these reasons, diagnosis, evaluation and treatment can be decisive in the development of children.
