The IB Diploma Programme (IBDP) is a challenging two-year educational program for students aged 16 to 19. It is internationally recognized and designed to develop students who are intellectually curious, globally aware, and well-prepared for university and beyond. The program includes six subject groups (such as languages, sciences, and mathematics), as well as three core components: Theory of Knowledge (TOK), the Extended Essay (EE), and Creativity, Activity, Service (CAS). These elements aim to foster critical thinking, research skills, and personal growth.
All of these components aim to develop the characteristics in the Learner Profile.
The registration process begins in August for incoming ninth grade students, and will be completed in the month of January for all students interested in the IB program at DCHS.
A candidate can only receive an IB Diploma if the following conditions are met.
6 Groups (Subjects)
3 - 4 HL Exams
2 - 3 SL Exams
The candidate has achieved at least 24 total points.
A grade of at least a 2 has been awarded in all subjects.
There are no more than two grade 2s awarded (SL or HL).
There are no more than three grade 3s or below awarded (SL or HL).
The candidate has at least 12 points on HL subjects. (For candidates who register for four HL subjects, the three highest grades count).
Candidates have at least 9 points on SL subjects. (Candidates who register for two SL subjects must be awarded at least 5 points at SL).
The diploma points are calculated by adding together the grades achieved from each of the six subjects and the core. Candidates receive a grade of 1-7 for each subject and up to three points for the core elements (EE and TOK). Standard level (SL) and higher level (HL) subjects are equally valued in determining the candidate’s final points. To achieve a diploma, students must earn at least 24 points and have met the conditions listed below.
The highest score that a candidate can achieve is 45 points. The maximum points of 45 is obtained from 6 (subjects) times 7 (top grade) plus 3 points from the core.
The IB curriculum at Douglas County High School consists of six subject groups:
Group 1 - Language & Literature (English). Including the study of selections from World Literature.
Group 2 - Language Acquisition - (second language) French and Spanish
Group 3 - Individuals & Societies - European History, Psychology and Philosophy
Group 4 - Science - Biology, Chemistry, Physics and Environmental Systems & Societies, Sports Exercise & Health Sciences (SEHS)
Group 5 - Mathematics - Analysis and Approaches, Applications and Interpretation
Group 6 - Arts - Music, Visual Art, Theater
To ensure both breadth and depth of knowledge and understanding, students choose courses from the following subject groups: studies in language and literature; language acquisition; individuals and societies; sciences; mathematics; and the arts. Most subjects may be taken at either standard level (SL) or higher level (HL).
SL courses ensure students are exposed to a range of disciplines that they might otherwise opt out of, and HL courses allow students to spend more time with subjects they are more interested in by exploring options in addition to the SL core curriculum. In this sense, all DP courses, regardless of whether they are SL or HL, are integral to the programme.
Both SL and HL courses are meant to span the two years of the DP. SL courses are recommended to have at least 150 hours of instructional time, and HL courses are recommended to have at least 240 instructional hours.
In most cases both SL and HL courses consist of the same educational aims, core syllabus and curriculum and assessment models. HL courses typically also include a range of additional elements designed to allow students to explore areas of interest within the subject in more depth. In this sense, SL courses are not watered down versions of their HL counterparts. The assessment criteria are equally demanding for both levels, and SL exams are marked and standardized with the same rigor as all IB coursework.
The International Baccalaureate® (IB) Diploma Programme (DP) uses both internally and externally assessed components to assess student performance. (Source)
Teacher assessment is used for most courses. This includes: oral work in languages, fieldwork in geography, laboratory work in the sciences, investigations in mathematics, and artistic performances. (Source)
IAs are given on a school and course determined schedule.
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.

EAs are given on a global schedule, spanning four weeks from April - May.
The extended essay is an independent, self-directed piece of research, finishing with a 4,000-word paper.
The extended essay provides:
practical preparation for undergraduate research
an opportunity for students to investigate a topic of personal interest to them, which relates to one of the student's six DP subjects, or takes the interdisciplinary approach of a World Studies extended essay.
Through the research process for the extended essay, students develop skills in:
formulating an appropriate research question
engaging in a personal exploration of the topic
communicating ideas
developing an argument.
Participation in this process develops the capacity to analyze, synthesize and evaluate knowledge.
An extended essay can also be undertaken in world studies, where students carry out an in-depth interdisciplinary study of an issue of contemporary global significance, across two IB diploma disciplines.

Theory of Knowledge (TOK) is a core class in the IB Diploma Programme that encourages students to reflect on how we know what we know. It explores different ways of knowing (like reason, emotion, language, and sense perception) and how knowledge is built across various areas of knowledge (such as science, history, and the arts).
The course helps students develop critical thinking skills by questioning the reliability, origins, and limits of knowledge. It doesn’t teach specific content but focuses on understanding and evaluating knowledge itself.
TOK is assessed through a presentation (on a real-world knowledge question) and a 1,600-word essay based on a prescribed title.

CAS (Creativity, Activity, Service) is one of the core components of the IB Diploma Programme. It encourages students to engage in a range of experiences outside the classroom to foster personal and interpersonal development.
Creativity involves exploring and extending ideas through artistic or imaginative activities.
Activity focuses on physical exertion that contributes to a healthy lifestyle.
Service requires students to engage with the community through unpaid, voluntary work.
Students must complete and reflect on experiences in all three areas throughout the two-year program, helping them develop skills like collaboration, perseverance, and empathy.
In order to demonstrate these concepts, students are required to undertake a CAS project. The project challenges students to:
show initiative
demonstrate perseverance
develop skills such as collaboration, problem solving and decision making.
