One of the most important things before children go to school is that they are ready for that step in emotional and sociological way. Children acquire their sociality with people and committed relations form the basis of the human community. In the game with peers they learn how to abide by various social rules, they also notice the traits of others and acquire an essential experience. Adopted social skills enable the child to be socially accepted by the people who surround him, which gives a child a message of respect and appreciation of its value. Appropriate social development requires knowledge and understanding of norms, rules and values of the community in which the individual lives, as well as the ability of effective interactions within that community. Emotions are there to facilitate the child to recognize themselves and their existence and to develop self-awareness, starting to differentiate themselves from others and having the need to be physically and emotionally close with people they are surrounded by. To get the child ready for school it must combine different abilities, such as skill, knowledge, habits and motivation. It is a great gain if the child is prepared to be socially competent and acquire the experience of separation from parents before school. Each child's individual skills develop differently and in every moment each child has their own strengths and weaknesses. In order for a child to develop properly it is necessary to have a harmonious relationship between biological factors from conception and childbirth and the influence of the wider and narrower environment in which the child lives. A study was conducted in one kindergarten on the girls and boys of preschool age. The aim of this study was to find out how many children are ready for school by certain characteristics and if there are any differences between the age and the gender group. Results shows that children are ready for school by both social and emotional characteristics. Even though some undeveloped skills they can learn in school while getting help from a school teacher. There were no significant differences regarding gender differences, in girls and boys, as with age differences it was shown that the period of one year is the key for children to make a progress in order to be ready for school.
