Question

A high school has started a community service program. Under the program, students must participate in volunteer activities, such as helping at an after-school program, visiting residents at a nursing home, and planting trees. The students who log the most service hours will receive a special designation on their diploma. What incentive did the school offer the students in this case?

*Figured out answer. "Recognition at graduation"

Answer 1

The answer could be recognition at graduation. However, it could also be gathering extra curricular activities points throughout the year and one could also have special awards during graduation such as best in leadership and the alike. Special awards allows the school to recognize specific students particularly and will give a standout when applying for jobs or masteral degrees.

Answer 2

I believe the answer is: recognition at graduation

The type of service that is eligible for recognition must be the type of services that are acknowledged by  the state of board of education.
If they are able to confirm the result of the services, the students would be graduated with honor.
