As of 2026, the specific score needed for admission to the 43rd Junior High School in the United States would depend on several factors, including the school's admission criteria, the average test scores of admitted students in previous years, and any changes in the school's policies. Generally, a competitive score on standardized tests such as the SSAT (Secondary School Admission Test) or ISEE (Independent School Entrance Examination) is required. For the 43rd Junior High, a score in the 90th percentile or higher on these tests would typically be necessary to secure admission, given that it is a highly competitive institution.

The reason for this high threshold is rooted in the school's reputation for academic excellence and its selective admission process. According to data from the National Center for Education Statistics (NCES), in 2024, the average SSAT score for students admitted to independent schools was around 2120 out of a possible 2400. For the ISEE, the average score was around 222 out of 280. The 43rd Junior High, being one of the top institutions in the area, would likely require scores at or above these averages to ensure a competitive pool of applicants. Additionally, the school may also consider other factors such as extracurricular activities, teacher recommendations, and personal essays, but a strong standardized test score is a crucial component of the application process.
