An In-Depth Look at Our International Baccalaureate Diploma Program

The International Baccalaureate (IB) Diploma program encompasses the most rigorous curriculum a private high school student can choose. The IB Diploma program is ideal for students who excel in academics and wish to challenge themselves intellectually. Quarry Lane School is the only private, college preparatory school in the East Bay area to offer the IB Diploma program.

Quarry Lane’s IB Diploma program enables students to select courses from six subject groups. These include Experimental Sciences, Second Language, English, Math, the Arts, and Individuals and Societies. Three to four courses are taken at the Higher Level; the remainder is taken at the Standard Level. This allows students to develop their particular academic interests. All of these courses span the junior and senior years. Some examples of courses a student might take include geography, economics, classical languages, mathematical studies, design technology, and business management. They may also choose from dance, film, music, theater, and visual arts. In addition, IB students at our private high school must complete all IB Core Requirements.

Core Requirements
There are three core requirements students must complete for the IB Diploma program: the extended essay, theory of knowledge (TOK) and creativity, action and service (CAS). The extended essay requires students to complete a self-directed 4,000-word essay that explores a topic of interest, and demonstrates exceptional research and writing skills. Students also take an interdisciplinary TOK class. In this course, students are expected to develop critical thinking skills and to reflect upon the nature of knowledge. The course is assessed with an essay and an oral presentation. Lastly, IB students at our private high school are expected to participate in our CAS program. The CAS program promotes enriching experiences outside the classroom, including community service work, artistic endeavors, sports activities, and other projects.

Quarry Lane School is pleased to offer the IB Diploma program to our private high school students. A student’s success in the IB Diploma program is contingent upon a high level of commitment from the student, parents, and teachers.

ESL Camping Trip

In the spirit of "Throwback Thursday", let's throw it back to the ESL camping trip last weekend. Nineteen of our international students, along with Ms. Clark and Ms. Cumberworth, went on an overnight camping trip to Lake Chabot to give our international students an outdoor, classic "American" camping experience. From pitching tents to sleeping in sleeping bags to making S'mores, it was a first-time, eye-opening experience for the all of the students. As Ms. Clark put it, "We came back a little dirtier, a little sleepier but a lot happier for trying something new and succeeding at it! Hopefully, this will become an annual tradition!"

The Quarry Lane ESL Summer Camp hosts a variety of half day excursions geared towards introducing new experiences, exploring the California landscape and building bonds with their peers. For more information, go to
