Academic Results

Our students' progress is assessed using a number of reputable tests and programs.

Standardized Assessment in Elementary and Middle School

In the Elementary and Middle School Houses, we implement the Northwest Evaluation Association (NWEA) Measures of Academic Progress (MAPs) tests. These tests are conducted electronically in close to a thousand international schools worldwide, in order to support students and teachers in their teaching and learning endeavors.

Our MAPs provide us with a wide range of information on how well our students are mastering standards-based content and skills compared with other schools, as well as comprehensive data on the learning growth of each individual student. Twice a year, our students in Grades 1 through 5 take tests in both Reading and Mathematics, and students in Grades 3 through 5 take an additional test in Language Usage.

The results are then analyzed and used to inform future teaching and learning. They are also used to help evaluate our programs and resources in order to ensure that we have quality frameworks in place to guide our teaching and learning as effectively as possible. 

GPA and Rank

GPA is calculated over a three-year period of grades 10-12. Only approved courses taken at Country Day School are calculated into the GPA. All online courses attached to the transcripts are from fully accredited providers.

Due to the small number of students in the class and the multicultural and varied scholastic backgrounds of our population, we do not rank our students.

AP and Honors Courses

Country Day School offers the following AP courses: Art, Biology, Calculus AB, Calculus BC, Chemistry, Comparative Government, English Language, English Literature, Environmental Science, Microeconomics, Macroeconomics, Psychology, Physics Part I, Statistics, Spanish Language, Spanish Literature, US History and World History. In addition, Country Day School offers the following honors courses: Integrated Math III, Pre-calculus, English 10, and Linear Algebra.

Costa Rican Baccalaureate Program

The Costa Rican Baccalaureate program (grade 12) is the Costa Rican Ministry of Education’s secondary school credential. This program and diploma enables students to study at universities in Costa Rica.

National Honor Society

Students with a cumulative high school average of 90% are candidates for National Honor Society. Students demonstrating scholarship, leadership, character and service are candidates for membership selection.
