Courses in Personal Social Health Education (PSHE) are required in grades 9 and 10. All students in grades 9 and 10 choose from four Visual and Performing Arts options: 2-D art, ceramics, instrumental music, and drama. Academic electives include IB Music and IB Art or a fourth year of any of the following: math, science, or language. Other twice weekly T/F electives available to the students are: computer graphics, yearbook, journalism, library assistant, choir, drama, environment club, and pottery. Special instruction in English as an Additional Language Language (EAL) is available through grade 10. Class size varies according to the subject. Helping Labs in writing, math, and science are offered to all students who want extra support in an area where they need further explanation or practice.
The grading system uses letter grades A-F with D (60%) a passing mark. Reports are sent to parents at the end of each of the four marking periods. Parents are advised if a student is in danger of failing a subject and teacher parent conferences are held to discuss ways in which a student can be supported in areas in whcih she may be weak. First Honors is A- (90%) and above and Second Honors is B+.
Students are grouped heterogenously except in mathematics courses, in which groupings are based on aptitude and achievement. The average course load is five classes in academic subjects and one elective.
Seisen has offered the International Baccalaureate Diploma program since 1986. Students are able to earn a full I.B. Diploma or to take individual courses for certificates. In grade 10 each student decides whether she will take the Seisen University Preparatory Program or the International Baccalaureate Program to complete her graduation requirements in the last two years of school. In most cases the students enrolled in both programs are in the same classes, but there are variations in the requirements, which are designed to meet the needs of the students and cater to their individual strengths and weaknesses.
The following tests are administered in the school: the PSAT/National Merit Scholarship Qualifying Test, SAT, IOWA Assessments, and IGCSE.
