Academic Calendar

Our academic calendar reminds parents of the important dates related to student learning. This includes report-card release dates, parent-teacher interviews and school breaks. Due to COVID-19 health and safety measures, our calendar is subject to change. Parents will be alerted of any changes via email.

CIS Parent Organization

The CIS Parent Organization (CISPO) was established to foster engagement between parents, faculty and staff. The school welcomes parents to join CISPO’s monthly meetups and community engagement activities. We hope to see you soon! 


We communicate with parents via schoolwide email updates, social media and its website. Teachers post daily classroom updates for parents in Seesaw (Nursery to Grade 5) and Google Classroom (Grades 6-10). We encourage parents to contact their child’s homeroom or advisory teacher directly with questions regarding your their academic, social and emotional progress.

Extracurricular Activities

A diverse selection of optional extracurricular activities (ECAs) are offered each year. From ceramics to language-based sessions, our program was created to cater to students with diverse interests. Information about ECAs, including registration details and pricing, is shared directly with parents via email. 

Gibbon Parent Portal

Gibbon is the school’s student information system. It gives parents instant access to their child’s timetable, attendance records and report cards.

Please contact if you have any questions or require assistance.

Lunch Program

We partner with the Dara Airport Hotel Restaurant to provide hot and healthy student lunches at our campuses. All meals are prepared on-site. Lunch menus are shared via our digital newsletter, the CIS Weekly.

Parents may register their child for the lunch program for a single semester or for a full academic year. Lunch program fees vary by grade level. Please see the CIS tuition and school fees schedule and contact for registration and payment information.

Parent Handbook

Preparing for school is a task for the whole family. With this in mind, CIS has compiled a guide to introduce parents and caregivers to the school’s policies, procedures, schedules, and classroom norms.
