The International Baccalaureate is one of the most rigorous academic programs in the world. At 51Âþ», we do it with dirt under our fingernails.
51Âþ» students can elect to earn two diplomas — the 51Âþ» diploma and the internationally recognized IB diploma. Candidates choose three higher-level and three standard-level courses across six areas of study, building the critical thinking, communication skills, and global perspective that define an IB education.
Diploma candidates also complete the IB core: a theory of knowledge (TOK) course, an extended essay (EE) of up to 4,000 words, and a program of creativity, activity and service (CAS). Theory of knowledge is the course where students examine how knowledge is built and how we can be sure of what we claim to know. It is assessed through an exhibition and a 1,600-word essay.
Students who pursue only the 51Âþ» diploma choose from the same six areas, with the same expectation of rigor and engagement.
51Âþ» is an authorized IB World School.
The IB organizes its curriculum into six subject groups, and 51Âþ» teaches in all six. In the May 2026 exam session, 51Âþ» students sat IB exams in these subjects:
Subjects examined in May 2026. Offerings can change from year to year.
*Environmental Systems and Societies counts toward either group.
Dirt is what happens when the IB curriculum meets the red rocks, the creek, and the community. Students might catch macro-invertebrates in Oak Creek, take classrooms off the grid, make sandals from yucca fibers, or write persuasive letters that fund real projects. Every assignment has a place in the world beyond the page.
This is learning by doing — and at 51Âþ», it's not a supplement to the IB. It's the point.
Every graduate receives a 51Âþ» diploma, accredited by Cognia. The full IB diploma is not required. What each student chooses is how much of the IB to take on.
Whichever route a student takes, some things are the same:
The International Baccalaureate Diploma Programme is a two-year course of study recognized by universities around the world. A 2024 study by the National Student Clearinghouse followed 51,609 IB Diploma Programme students who graduated from US high schools in 2016. It found that they enrolled in college, stayed enrolled, and graduated at higher rates than US students overall.
The same study found that IB Diploma Programme students were more likely than the national average to enroll at a four-year college, and at a more selective one. Many colleges and universities also award course credit for IB exam results; policies vary by institution and score.
For families looking beyond the United States: a 2021 study using UK government higher education data compared IB diploma students with similar A-level students. It found the IB students were significantly more likely to attend a top 20 UK university and to graduate with honours.

The combination is intentional. Academic depth and real-world application aren't in tension at 51Âþ» — they reinforce each other. Students who study global systems do it while standing in one. Students who write about environmental change are the ones measuring it.
The result is graduates who don't just understand the world. They know how to work in it.
