        <Explanation>The international baccalaureate organization ("IBO") provides short-term grants for schools experiencing temporary financial challenges or schools that are demonstrably increasing access to IB programs. The grants to schools or education districts are offered in two categories. Category 1: IB world schools experiencing temporary financial difficulties owing to unpredictable circumstances beyond their control. Category 2: IB world schools or implementing schools that can clearly demonstrate that they are significantly widening access to IB program(s) and/or that they will be significantly contributing to a more diverse, inclusive IB community. Grants are short term, valid for one year with a possible extension to two years maximum. Funds can be used for the training of teachers and administrators, the payment of the ib annual school fee for one or more programs, or to support creative schemes to widen access and diversity. Grants take the form of a credit to the school's IB account. This enables a rebate in annual fees or payment of workshop expenses in lieu of reimbursement of costs incurred through schemes to widen access and diversity. Schools are expected to submit a report after the funds have been expended. Schools are not normally eligible for more than two awards.</Explanation>
