The College Board: Connecting Students to College Success
The College Board is a not-for-profit membership association whose mission is to connect
students to college success and opportunity. Founded in 1900, the association is composed
of more than 4,700 schools, colleges, universities, and other educational organizations. Each
year, the College Board serves over three and a half million students and their parents, 23,000
high schools, and 3,500 colleges through major programs and services in college admissions,
guidance, assessment, financial aid, enrollment, and teaching and learning. Among its best-
known programs are the SAT®, the PSAT/NMSQT®, and the Advanced Placement Program®
(AP®). The College Board is committed to the principles of excellence and equity, and that
commitment is embodied in all of its programs, services, activities, and concerns.
Equity Policy Statement
The College Board believes that all students should be prepared for and have an opportunity
to participate successfully in college, and that equitable access to higher education must be a
guiding principle for teachers, counselors, administrators, and policymakers. As part of this,
all students should be given appropriate guidance about college admissions, and provided
the full support necessary to ensure college admission and success. All students should be
encouraged to accept the challenge of a rigorous academic curriculum through enrollment
in college preparatory programs and AP courses. Schools should make every effort to ensure
that AP and other college-level classes reflect the diversity of the student population. The
College Board encourages the elimination of barriers that limit access to demanding courses
for all students, particularly those from traditionally underrepresented ethnic, racial, and
socioeconomic groups.

Statistics
The Student Performance Q&A for the 2005 exam (available on AP Central this fall) provides
valuable information on areas in which students continue to need attention. In general, on the
free-response questions students need to be encouraged to show all of their work and justify their
answers. Sample student responses with corresponding commentary on AP Central should also
add to teachers’ and students’ understanding of what is expected on these questions. More details
on student performance in 2005, in all content areas of the exam, can be found on AP Central.
