The paper aims to highlight the characteristics of the behavioral manifestation in the 5 to 6 years old preschoolers. The study involved 20 children aged 5 to 6, corresponding to level 2 (upper group) from the half-day kindergarten attached to the ”Maica Domnului” Middle School of Bucharest. The study was conducted throughout the 2020-2021 school year. The essential pedagogical tools, used for an individualized evaluation of education and learning, offered a series of behavioral manifestations, which identified both skills and difficulties of each child separately. In this regard, the sheet for assessing the individual progress of the child was applied at the beginning and the end of the 2020-2021 school year. The purposes of the early education at primary cycle level are related to 5 areas: 1) physical development, health and personal hygiene; 2) socio-emotional development; 3) development of language, communication and premises of reading and writing; 4) cognitive development and knowledge of the world; 5) abilities and attitudes in learning. Depending on the results obtained in the initial testing, a plan with improvement measures was proposed for each development area. The results of the study highlight the characteristics of the behavioral development indicators manifestation in the preschoolers aged 5-6 years. The analysis of the indicators specified in the sheet shows the individual behavioral development level of each child and the group level at the end of the preschool period.
