In order to be admitted to the school, the student must submit the required ISE documents to the main ISE office. An interview with the parents will follow the entrance test. A decision on acceptance, grade placement and date to start classes will be made after completion of the admissions process. When a student is accepted, a place is offered in a specific grade level. The family should confirm acceptance. The accepted family will visit the ISE business office personnel regarding payment. The accepted family will visit the ISE bookstore for uniform and student supplies.

Numerous activities are offered either after school or during the activity block in the middle and high school.

ISE relies on Standards Based Grading, which is a system that reports student proficiency in a number of specific learning goals or standards. This system gives students an achievement level that represent their proficiency in each of the skill assed rather than giving students one grade on a particular class.

Below is a description of achievement levels, as part of the school's standards based report cards:

• Exemplary (EX) – This rare level of achievement describes evidence that demonstrates exemplary performance in relation to the standards.
• Proficient (PR) – This level of achievement describes evidence that demonstrates mastery performance in relation to the standards.
• Approaching (AP) – This level of achievement describes evidence with some mastery in relation to the standards.
• Concern (CO) – This level of achievement describes evidence that demonstrates limited mastery in relation to the standards.
