Appropriations for the program shall be used by the department on behalf of participants in each fiscal year to pay public two-year and four-year institutions of higher education or other publicly funded training programs in the state for benefits extended to participants by the Fostering Hope program. The department may also use not more than 10 percent of the total state appropriation made to the program in any fiscal year for costs associated with the mentor service. The department may not spend appropriations for the program for purposes other than those listed in this section. Any monies appropriated to the department for Fostering Hope that are unspent at the end of a fiscal year shall be carried over for use by the program in the next fiscal year. The department shall develop rules for ensuring that expenses of the Fostering Hope program in a fiscal year do not exceed funding for the program in that fiscal year. For that purpose, and any other provision of this chapter to the contrary notwithstanding, the department may limit the acceptance of applications for Fostering Hope scholarships and may limit the award of scholarships.
