Objective: In this study, it was aimed to determine the level of first aid information of primary and secondary school teachers. Method: The universe of this descriptive study consisted of teachers (n=151) working in 4 primary schools with the same socioeconomic level in Çiğli and Karşıyaka districts of İzmir province where school health studies were conducted. A total of 116 teachers who were providing education in the first and second grades of the primary school participated voluntarily in the research survey. Information Form (incl. age, gender, branch, place of employment, status of first aid education and place of education) and First Aid Information Assessment Form (32 questions) were used in the research. Results: In the survey mean first aid information score obtained by the teachers over a total of 32 points was determined as 22.98±3.87 points. According to the First Aid Information Form, the highest score was obtained by the teachers in the 25-34 age group (24.32±1.95) It was determined that the information score decreased with increasing age, and as a result of advanced analysis, the difference in knowledge levels was stemmed from the scores of the teachers in the 55-60 age group (p<0.05). Besides, the scores of the teachers who received first aid training were statistically significantly higher than those who didn’t (mean scores: (23. 81±2.3 vs 21.46±5.38). It was determined that there was no statistically significant difference in the First Aid Information Evaluation Form scores according to the teachers’ branches (p>0.05) (Table 5). Conclusion: Teachers’ first aid information is at a moderate level. It was determined that the teachers’ scores decreased with increasing age and the scores of teachers who received first aid training were higher than those who did not.
