From information provided by the United States Office of Education (USOE), 1,063 public, private, and parochial senior high schools were asked to participate in Project Talent. Of these schools, 987 (93 percent) agreed to take part. Selected schools were intended to reflect the diversity of the American high school experience. With the exception of New York City and Chicago schools, every student in a participating school became part of the study. All 9th-graders in the junior high schools associated with participating senior high schools were also included. 238 junior high schools were part of Project Talent, bringing the total number of randomly selected schools to 1,225. In addition, 128 schools asked to participate in the study as "volunteer" schools, bringing the total number of schools in Project Talent to 1,353.
