Sensory integration is a neurological process that organizes sensations from one's own body and the environment in a way that makes the body efficient in the environment. Good sensory integration is important for various functions such as attention, learning, motor planning, selfregulation, and many others. Sensory processing disorder is a condition where the brain has difficulty receiving and processing sensory information and it may not only occur alongside already diagnosed conditions such as autism or ADHD but also in typically developing children. When discussing sensory integration, it is very important to be familiar with the concepts of hyposensitivity and hypersensitivity, as well as with all eight sensory systems and how hyposensitivity and hypersensitivity manifest in relation to each sensory system. The preschool period is very significant for children and their development, and for this reason, preschool teachers play an important role as they spend the most time with children and can point out any difficulties or suspicions of a difficulty. To determine the awareness of preschool teachers and students of early childhood education about the importance of sensory integration, a study was conducted. Awareness was assessed using a constructed survey questionnaire via Google Forms. The sample included 52 participants, of which 27 were teachers and 25 were students. Quantitative data analysis showed that the respondents are aware of the importance of sensory integration for child development and that there is no statistically significant difference in awareness between preschool teachers and students of early childhood education. There are some similarities in the responses between these two groups, for example, both teachers and students most frequently get informed about new developments in the field through informal conversations with colleagues, but there are also some differences: teachers most commonly heard about sensory processing difficulties through formal education they attended, while students heard about this term in informal conversations with colleagues.
