The article investigates the results of grade placement of biology in the high school curriculum in science education in the U.S. This article speculates that the conflicting results or earlier investigations were due to the fact that the subjects were specially selected. This study indicates that schools can effectively offer biology in the ninth grade. In addition, this paper points out that it was advantageous for students because it will allow them to take more courses of their own choosing.
