Aim: The aim is to assess the level of awareness of hyperactivity and attention deficit disorder in children among the first and third year nursing students. The research should also determine whether there are differences in student awareness regarding their gender, age, secondary education, years of study (first and third), working status and years of work experience. The draft of the study: The research was conducted as a cross-sectional study. Examinees and Methods: The study included 76 undergraduate nursing students of the first and third year. Most of the respondents are unemployed and have previously finished nursing school. A questionnaire consisting of 2 open-ended questions, 5 closed-ended questions, and 20 statements about hyperactivity disorder was used. Results: Third-year nursing students showed better knowledge responding to the statement that ADHD children have problems in controlling their behavior, where 96,2% agreed with the statement. Third year students responded better to the claim that ADHD children often switch from one activity to the next without finishing the previous one (p = 0,011). Significant majority of third year students agrees that ADHD is only effectively treated with pharmacotherapy (p = 0,048). Younger respondents believe that a hyperactive child should be punished for their actions (p = 0.011), while older respondents are better informed that children with ADHD require multidisciplinary approach and care (p = 0.002). Conclusion: There were differences in the level of awareness of ADHD between nursing students based on their age and year of study, while differences were not found in terms of gender, work, and secondary education.
