The aim of this study is to evaluate science teacher candidates based on bioethical values, scientific literacy level and empathy skills and to determine their associations. Therefore, descriptive model was used for the study. The sample of the study consists total of 286 teacher candidates from first, second, third and fourth grade of Faculty of Education Science Teaching department. Results of the study revealed that bioethical values for "Benefits of Biotechnology Applications", "Science and Ethics", "Reproductive Technologies and Cloning", "Controlling the Genetic Interventions" subscales were increased with school year in science teacher candidates. In addition, science literacy of science teacher candidates for "Nature of Science" and "Science-Technology-Society Relation" subscales were also increased with school year. The study also found a positive relation between bioethical values for two subscales of bioethical values, "Benefits of Biotechnology Applications" and "Controlling the Genetic Interventions", and science literacy for "Nature of Science" subscales in science teacher candidates. Similarly, a positive relation was found between bioethical values for two subscales, "Benefits of Biotechnology Applications" and "Controlling the Genetic Interventions", and science literacy for "Science-Technology-Society Relation" subscale in science teacher candidates. Analysis results showed a positive relation between bioethical values and empathy skills of science teacher candidates. In other words, the higher the teacher's empathy skills, the higher their bioethical values.
