"The Scale Parental Information Needs in Transition to Kindergarten" was used to determine the parents' needs. Results: It was found out that the families need all of the information related to transition to pre-school institutions. Except the educational state of the mother, the socioeconomic level of the family, the gender of the child and the participation of the child's father to the educational program, it was found out that the other demographic factors do not lead to any significant differences in the needs (p 0.05).
