The Outstanding Senior Scholarship Award is sponsored by the CMIS Parent Teacher Group (PTG). It is a merit-based cash award in the amount of 30,000 baht, granted to the member of the senior class who best demonstrates outstanding achievement, both at CMIS and in the broader community. The award recipient is selected by a committee, which includes representatives from the CMIS faculty, administration, PTG executive membership, and a CMIS parent (who does not have a child in the senior class).
