All students are automatically issued ID cards once they start at CMIS. These ID cards are issued every odd numbered calendar year (school years starting in 2021, 2023...) through the Front Office. If students lose their ID card before it has expired, they will need to go through the Front Office to get a replacement. There is a 100 baht fee for this. The new ID card should be available for students to pick up at the Front Office 3 school days after they have paid the replacement fee. The ID cards also serve as Library cards for the students.
