Each September, HOBY Sophomore Registration Kits are sent to over 22,000 public, private and charter high schools in the United States. All tenth graders are eligible for selection to attend one of the three- or four-day weekend seminars held in their area each spring. A sophomore leader may be selected by each school and is certified by the principal. Mid Florida HOBY does not dictate how each school’s representative is selected. Some schools use an essay or interview process, while others simply select a student. The school’s contact person preliminarily registers the student in the online registration system. In certain circumstances, multiple students from each school may be able to attend.
