Following an American-based curriculum while offering many advanced placement classes


Oasis International School graduates earn a high school diploma that is recognized and accepted worldwide. We are accredited by Middle States Association of Colleges and Schools and are fully approved by the Turkish Ministry of Education. Our school uses a 4.0 grading scale in alignment with the College Board and teaches through a normal American curricular system.

While all of our classes are taught in English, our student body is incredibly diverse. Over the years Oasis has been home to students from more than 100 countries.

In the last 16 years, five Oasis students have earned U.S. National Merit recognition, including a National Merit Finalist and a National Merit Scholar. Nearly all Oasis students continue their education at a college or university in North America, Europe, or Asia.

AP® is operated by the College Board, an organization whose mission is to connect students to university success and opportunity. The College Board also administers the PSAT/NMSQT® and SAT®.

The AP® program provides students with university-level academic courses, giving them a head start when entering tertiary education. Students who take AP® courses show universities they are serious about their education and are capable of performing well at the university level. AP® students refine their critical thinking, time management, and study skills while still in high school.

Due to their rigorous nature, AP® courses earn higher grade point averages. Additionally, by earning university credits while in high school and skipping introductory courses when starting university, students can easily save money on tuition, study abroad, or double major. Lastly, AP® class sizes are typically much smaller than regular courses, allowing students to have more individualized instruction from their specially-trained teachers.

  • AP US History
    The AP® U.S. History course focuses on the development of historical thinking skills (chronological reasoning, comparing and contextualizing, crafting arguments using evidence, and interpreting historical narrative) and the development of students’ abilities to think conceptually about U.S. history from approximately 1491 to the present.
  • AP Psychology
    The AP® Psychology course introduces students to the systematic and scientific study of human behavior and mental processes. Students explore the biological bases of behavior, sensation and perception, learning and cognition, motivation, developmental psychology, testing and individual differences, treatment of abnormal behavior, and social psychology.
  • AP Human Geography
    The AP® Human Geography course explores how humans have understood, used, and changed the surface of Earth. Students will use the tools and thinking processes of geographers to examine patterns of human population, migration, and land use.
  • AP Pre-Calculus
    The AP® Precalculus course prepares students for other college-level mathematics and science courses. Students explore everyday situations using mathematical tools and lenses, developing an understanding of modeling and functions, and examining scenarios through multiple representations. The course framework outlines content and skills needed for careers in mathematics, physics, biology, health science, social science, and data science.
  • AP Calculus AB
    AP® Calculus AB is roughly equivalent to a first semester college calculus course devoted to topics in differential and integral calculus. The AP® course covers topics in these areas, including concepts and skills of limits, derivatives, definite integrals, and the Fundamental Theorem of Calculus.
  • AP Calculus BC
    AP® Calculus BC is roughly equivalent to both first and second semester college calculus courses. The AP® course covers topics in differential and integral calculus, including concepts and skills of limits, derivatives, definite integrals, the Fundamental Theorem of Calculus, and series.
  • AP English Language and Composition
    The AP® English Language and Composition course aligns to an introductory college-level rhetoric and writing curriculum, which requires students to develop evidence-based analytic and argumentative essays that proceed through several stages or drafts. Students evaluate, synthesize, and cite research to support their arguments.
  • AP English Literature and Composition
    The AP® English Literature and Composition course aligns to an introductory college-level literary analysis course. As they read, students consider a work’s structure, style, and themes, as well as its use of figurative language, imagery, symbolism, and tone. Writing assignments include expository, analytical, and argumentative essays that require students to analyze and interpret literary works.


Honors classes cover the same or similar material as regular classes but provide more depth and insight into the subjects at hand. More challenging content means studying takes more time, projects require more work, and tests are more challenging.

As a result, honors students can develop better study habits and more effective test-taking skills. Fast-paced and interactive honors classes can also simulate a college classroom better than regular classes. Through Honors Classes, students may increase their GPAs up to a 4.5/4.5
