A Description of the International Baccalaureate (IB) Diploma Program and Advanced Placement (AP) Program

Element IB Diploma Program AP Program
What is it? The IB program is a rigorous pre-university program leading to assessment in six subject areas. IB is noted for its challenging curriculum and international perspective. Beyond completing college-level courses and examinations, IB students are also required to engage in community service, individual research, and an inquiry into the nature of knowledge. The AP program is a challenging academic program designed to provide motivated high school students with college-level academic courses. The AP program is a cooperative educational endeavor between secondary schools and colleges and universities and is considered a standard for academic excellence in the U.S.
Mission “The International Baccalaureate Organization aims to develop inquiring, knowledgeable and caring young people who help to create a better and more peaceful world through intercultural understanding and respect. To this end the IBO works with schools, governments and international organizations to develop challenging programs of international education and rigorous assessment. These programs encourage students across the world to become active, compassionate and lifelong learners who understand that other people, with their differences, can also be right.”

“The College Board’s mission is to connect students to college success and opportunity. The AP program supports the principle that each individual school must develop its’ own curriculum based on a set of expectations that colleges and secondary school faculty nationwide have established for college-level courses.” 

“For over 100 years, the College Board has partnered with leading educators, schools, and colleges to create innovative programs that help students, families, and educators to evaluate each student's academic strengths; challenge students to explore their interests and reach their potential; inspire students to do their best work; and pursue educational opportunities beyond high school.”

Courses IB course curriculum is developed by an international committee of university professors and master secondary teachers. IB standard level (SL) courses provide breadth while IB higher level (HL) courses provide specialization. All HL courses are two years. Some SL courses are two years and some are one year; these will also vary by school. IB requires 150 teaching hours for SL and 240 teaching hours for HL courses. FCPS offers 30 different IB courses at the HL and/or SL levels. Individual teachers develop their own curriculum based on established course requirements and AP standards that must be approved by the College Board as part of the AP Course Audit process. University professors review the course syllabi for rigor and content to match college standards. All AP courses are one-year. FCPS offers a total of 33 different AP courses in all of their AP schools.

A student must achieve a minimum score of 24 out of 45 points to be awarded the IB Diploma. Students may also take IB courses in areas of academic strength and interest. IB diploma course students take one or more IB courses and the associated exam(s) and receive certificates recognition for each IB exam with a score of “4” or better.

Community service is a requirement of AP Government.
Examinations Students take a series of internal assessments (assessed by the local teacher and moderated by an examiner) and external assessments (moderated by international standards). IB tests are scored on a scale of 1-7. Teachers predict student grades, and examinations are rescored if there is more than a one-point discrepancy. Several FCPS teachers are IB examiners. Students sit for an examination at the end of the AP course. AP tests are scored on a scale of 1—5. All examinations are graded by a group of AP readers. Many FCPS teachers are AP readers.
Types of
Assessments include lab work for science; papers for English and the social sciences; oral presentations or exams in English and foreign (world) languages; portfolios in math and computer science; and various projects such as journals and art books in the electives.
