From the author: School maturity, or more simply put, readiness for school learning is a psychological and pedagogical concept. It means that the level of physical, psychological and social development of the child corresponds to modern pedagogical requirements. And, according to the definition, school readiness includes several components, namely: physiological readiness, psychological readiness and social readiness.
