The contest fees students pay to Competitive Kids STEM for hosting competitions are non-refundable. Our organization pays a cost to the various external organizations that own these competitions to be allowed to host them. Contests require significant time and resource investment, not to mention the various charges paid for processing these payments to external organizations, multiple third parties, and financial institutions.

As a nonprofit organization, CKSTEM operates very leanly and has limited resources to keep our operating costs low to make our offerings available at a much lower cost to the students. Hence, we cannot offer any refund for contest fees to students for withdrawals or cancellations beyond our control.

If CKSTEM has wrongly charged any student, or we cancel an event due to reasons under our control and we receive refunds from external organizations, we will happily refund the fees paid by the students. Please note that processing charges could be deducted from the refund amount.
