This descriptive study aimed to determine the level of knowledge about parasitic diseases of the Vocational School of Health students who will be health care providers in future to provide health services to the public. The sample of our exam was comprised of the 229 students straining in Department of Midwifery, Department of Nursing and Department of Health Officers during the summer time at Eskisehir Osmangazi University. The students were asked to fill out the previously-devised questionnaire forms including 36 parasitic diseases questions under supervision. Each of these questions was given one point and the scoring scale ranged between 0-36. The scores were first categorized into two groups through K-means analysis and then Roc analysis was undertaken based upon these groups. As for the statistical analysis, the Chi-square test was employed and the criterion for statistical significance was determined as P<0.05. The age of the participants varied between 19 and 28, the mean age of whom was 21.39±1.61 years. The knowledge determined to be known most accurately was that "Disinfection of the drinking water is effective in protecting against parasitic diseases", a fact known by 92.6 percent of the participants. On the other hand, the least known knowledge was that "It is possible to get immunized against parasitic diseases via inoculation, a fact known by only 29.3 percent of the students. The scores for the knowledge of the students about parasitic diseases varied between 0 and 36, the mean of which was 24.80±6.63. The number of the students with sufficient knowledge about parasitic diseases was determined to be 159 (69.4%). The ratio of having sufficient knowledge about parasitic diseases was higher in female students, particularly those in Department of Nursing and Department of Midwifery, as well as in the first grade students and those whose mothers had at least secondary school education. The points given in these 4 groups achieved statistical significance (P<0.05)
