IB Diploma Programme

International Baccalaureate Program logoDexter High School became an accredited IB Programme in 2011, with the first diploma recipients graduating in 2014. Seventy-nine percent of candidates earned the Diploma. This exceeds the United States historical average and meets the worldwide historical average. This achievement is particularly impressive for a first-year program and is unmatched by comprehensive high schools belonging to International Baccalaureate Coordinators of Michigan.

About the International Baccalaureate Programme

The International Baccalaureate® (IB) is an international, non-profit educational foundation founded in 1968. There are currently 834 schools in the United States with IB diploma programs (only 30 in Michigan), and the credential is recognized in 75 countries at more than 2000 universities and colleges. The IB Diploma Programme is an academically rigorous two-year course for students ages 16-19 years. The curriculum includes six rigorous two-year courses, a 4,000 word Extended Essay, Theory of Knowledge course, and the CAS project: Creativity, Action, and Service, which gives students hands-on experience planning and executing service programs that integrate what they've learned in their IB studies. Student projects, essays, and exams are graded by external IB evaluators.

IB Curriculum

The International Baccalaureate® (IB) Diploma Programme (DP) has three core components:

  • Theory of knowledge, in which students reflect on the nature of knowledge and on how we know what we claim to know.
  • The extended essay, which is an independent, self-directed piece of research, finishing with a 4,000-word paper.
  • Creativity, action, service, in which students complete a project related to those three concepts.

The core components are are studied alongside individual subjects throughout a student’s time in the programme. Students choose a course from within each of the six subject groups:

  • Studies in language and literature
  • Language acquisition
  • Individuals and societies
  • Sciences
  • Mathematics
  • The arts

Each subject group offers several courses. Students may opt to study an additional sciences, individuals and societies, or languages course instead of a course in the arts.

Students will take some subjects at higher level (HL) and some at standard level (SL).  HL and SL courses differ in scope but are measured according to the same grade descriptors, with students expected to demonstrate a greater body of knowledge, understanding and skills at the higher level. Each student takes at least three (but not more than four) subjects at higher level, and the remaining at standard level. Standard level subjects take up 150 teaching hours. Higher level comprises 240 teaching hours.

For most courses, students take written examinations at the end of the DP. In many programme areas, students complete externally assessed coursework.

IB Assessment

Diploma Programme assessment procedures measure the extent to which students have mastered advanced academic skills in fulfilling these goals, for example:

  • analyzing and presenting information
  • evaluating and constructing arguments
  • solving problems creatively.

Basic skills are also assessed, including:

  • retaining knowledge
  • understanding key concepts
  • applying standard methods.

In addition to academic skills, DP assessment encourages an international outlook and intercultural skills, wherever appropriate. Student results are determined by performance against set standards, not by each student's position in the overall rank order. The IB uses both external and internal assessment in the DP.

External Assessment
Examinations form the basis of the assessment for most courses. This is because of their high levels of objectivity and reliability. They include:

  • essays
  • structured problems
  • short-response questions
  • data-response questions
  • text-response questions
  • case-study questions
  • multiple-choice questions – though these are rarely used.

Internal assessment
Teacher assessment is also used for most courses. This includes:

  • oral work in languages
  • fieldwork in geography
  • laboratory work in the sciences
  • investigations in mathematics
  • artistic performances.
