Any individual that will serve as an assistant for a student in any capacity on test day:
+ MUST be at least 18 years of age
+ CANNOT be a family member or guardian of the student
+ CANNOT be any individual that has served as an SSAT tutor for the student (private or school-based tutors who have not worked with a student in this capacity are okay to assist otherwise)
+ CANNOT be any individual who has or will coach the student in athletics or mentors/participates with the student in any other extracurricular activities.
Ultimately, the goal is to avoid having anyone with a vested interest in the student's performance on the SSAT work with the student on test day.
