The Sheriff's Reserve Program is the Ada County Sheriff's Office's way to allow for civilians to join the Office part-time, meaning without specific quota requirements, with the caveat that Sheriff's Reserve Deputies cannot promote beyond the Deputy rank.

As of the 20th March, 2026, the Sheriff's Reserve Program is only in place for what the Sheriff's Office considers, "Honoured Members."
