The United States has a robust system for identifying and nurturing students with special talents, particularly in the context of middle school entrance exams. The primary avenues to check for special talent students in these exams include:

1. Standardized Testing: Many middle schools use standardized tests like the Independent School Entrance Examination (ISEE) or the Secondary School Admissions Test (SSAT) to assess a student's academic abilities. These tests often have sections that identify students with exceptional skills in areas such as mathematics, verbal reasoning, and analytical writing.

2. Gifted and Talented Programs: Public schools often have Gifted and Talented (G&T) programs that specifically identify students with advanced abilities in various subjects. These programs may require additional assessments or recommendations from teachers or counselors.

3. School District Programs: Some school districts offer specialized programs for students with special talents. These programs may include advanced coursework, enrichment activities, or opportunities to participate in competitive events.

4. Teacher and Counselor Recommendations: Teachers and counselors play a crucial role in identifying students with special talents. They often observe students' performance in class, their engagement in extracurricular activities, and their overall academic potential.

5. Parental Input: Parents can also provide valuable insights into their child's abilities and interests. They may notice exceptional skills or talents that can be further explored through educational programs or assessments.

According to a report by the National Center for Education Statistics (NCES), approximately 7.8% of students in the United States were identified as gifted and talented in 2016. This indicates a significant number of students who possess special talents that can be nurtured through appropriate educational opportunities. The identification of these students is crucial for ensuring they receive the support and challenges necessary for their academic and personal development.
