Which of the following can be used to supplement training revenue?

Grants are a vital source of supplemental training revenue as they provide funding for specific programs or initiatives. These funds often come from government agencies, foundations, or other organizations aimed at supporting education and training within the community. By securing grants, training programs can enhance their offerings, cover operational costs, and expand their reach without placing additional financial burdens on participants.

This approach allows organizations to initiate or sustain training programs that might otherwise lack the necessary resources. While other methods, such as increased participant fees or lowering expenses, can influence revenue, grants specifically target the enhancement of training initiatives, making them a critical component in funding education and training efforts.
