AIM: It was aimed to evaluate the efficiency of the three days module given to the assistant health personnel working in 112 ambulances. METHODS: It was assumed that all the personnel working in the 112 ambulance systems under the health directory of Kırıkkale city would be involved. Theoretic and practical first aid training was given to all the personnel attending to the course in 6 groups of 20-25 with duration of 3 days for each. A 50 itemed questionnaire was applied to all the groups before and after the training. RESULTS: 132 people working in ambulance system in Kırıkkale city were involved in training. 63.6% of the personnel involved in the study were male and 66% were married. When they were grouped according to age, it was determined that 44% of them were in 26-35 age group. When they were grouped according to branches, it was determined that 47% of them were emergency medical technician (EMT) and 40.2% were health officer. When their level of education was taken into consideration, it was determined that 53% of them were graduates of high school and 43.2% were graduates of associate degree. 50.8% of all the personnel had a job experience of 1-5 years. When all the groups were evaluated together, there was a statistical meaningful difference (p<0.001) between pretest success grade (29.58±6.74) and posttest success grade (39.81±4.68). When EMT, paramedics and the other groups were compared; there was a pr test grade difference(p=0,003) between EMT and paramedics group(31,55±6,52) and the others&#8217; group(27.70±6.4). There wasn&#8217;t a grade difference between EMT, paramedics group and the others&#8217; group in posttest (p=0.765). CONCLUSION: The occupational training module which was done in a limited time was determined to be effective in providing a meaningful positive difference in knowledge level and providing personnel knowledge level standardization.
