In the United States, ninth-grade students typically take a variety of subjects, each contributing to their total scores. These subjects generally include English Language Arts (ELA), Mathematics, Science, Social Studies, and Foreign Language. Additionally, some students may also take elective courses such as Fine Arts, Physical Education, or Career and Technical Education (CTE) courses.

The inclusion of these subjects is designed to provide a comprehensive education that covers essential academic areas. English Language Arts and Mathematics are foundational subjects that are crucial for success in higher education and the workforce. Science and Social Studies provide students with a broader understanding of the natural and social worlds, respectively. Foreign Language courses are increasingly being offered to promote global awareness and communication skills. Electives allow students to explore their interests and develop skills in areas outside the core curriculum.

Data from the National Assessment of Educational Progress (NAEP) reveals that the average scores in these subjects can vary significantly across different states and school districts. For instance, in 2019, the average scale score in eighth-grade mathematics was 292 out of 500, while the average scale score in eighth-grade reading was 266. These scores reflect the overall performance of students in these subjects at the end of eighth grade, which is a precursor to their ninth-grade performance.

The importance of these subjects is further underscored by the fact that they are often used as indicators of college and career readiness. For example, the ACT and SAT, which are standardized tests required for college admission in the United States, assess students' knowledge and skills in English, Mathematics, Reading, and Science. Therefore, a strong foundation in these subjects in ninth grade can significantly impact a student's future academic and career opportunities.

In conclusion, the subjects with total scores in ninth grade in the United States are English Language Arts, Mathematics, Science, Social Studies, and Foreign Language, with the possibility of additional elective courses. These subjects are chosen to provide a well-rounded education that prepares students for higher education and the workforce. Data from NAEP and standardized tests like the ACT and SAT highlight the importance of these subjects in determining a student's readiness for future challenges.
