In the 1990s, great discoveries in the field of brain development came in the nineties. It emphasizes the importance of early and early experiences that influence the growth and development of neurological pathways (Kotulak, 1996, according to Shonkoff and Meisels, 2003). Early screening is a short and fast child development test, and is intended for use across the population to detect children with potential developmental disabilities in a timely manner. A systematic early screening is also required. Early children have enormous potentials and their current state does not have to be a reflection of all his competences, especially if he has just discovered the problem. Acquiring functional skills takes place through a large number of repetitions in everyday situations when these skills are used ie we need to enable a child and create opportunities to train these skills in various situations during a "normal" day. The role of early intervention professionals is no longer just a concern for the child and his needs but is now a teacher sharing his knowledge and skills with the family and supporting them (Lucas et al., 2010). Parents are most often the first to behave behaving less or less than what is expected for a certain developmental age. Previous research has used a variety of measuring instruments to determine which development stage the child has reached in areas such as fine motor, rough motor, communication, problem solving, socio-emotional area. However, research has not shown parental perceptibility to notice early developmental deviations. Also one of the shortcomings is the lack of expert support offered to parents during their early childhood. The AEPS® instrument for young children and newborns was used for this study (Bricker et al., 2007). AEPS® is more than an assessment tool, it is a comprehensive and interconnected system that actively involves family throughout the process, ranging from assessment to intervention. The second instrument is the ASQ 60 months that served the purpose of the research, a test of early screening and used for early screening of developmental deviations. The aim of this study is to examine whether there are differences in the results of a pragmatic criterion test carried out by an educational rehabilitator and a screening test on early developmental disruption by parents. Also, with the ASQ instrument 60 months, there was an investigation of the concerns of parents in certain development areas.
