This study aimed to develop a standard laboratory equipment list for biology preservice teachers and to determine their knowledge levels regarding these instruments. The study employed a quantitative research approach based on the descriptive survey model. The research was conducted with fifteen field experts and seventy-one biology preservice teachers. Expert opinions were analyzed using the Content Validity Ratio (CVR) method developed by Lawshe, with a critical value of 0.49 taken as the threshold. The analyses identified fifteen of the twenty-six instruments as essential for preservice biology teachers to learn during their training and use in their professional teaching, projects, and research. The findings indicated that the highest recognition and understanding levels were related to the light microscope, whereas lower knowledge levels were observed for the electrophoresis, pH meter, and spectrophotometer. The results suggest that preservice teachers acquire knowledge not only at a recognition level but also in a functional manner, providing insights into strengthening laboratory competencies in biology teacher education programs.
