Does anyone have parameters that they follow for fitness to serve requirements or have an age limit for volunteers (young or old)?  

We have a minimum age of 15, with minimum of 18 a requirement for a few placements. As far as "fitness to serve" we've had some very capable 80+ volunteers and others we've had to retire primarily due to memory issues. We don't have a specific policy around it but know that our responsibility is to the safety and care of everyone who comes through our doors. We've also had cases when we've reassigned a younger (under 80) volunteer because they weren't able to perform the duties of a role - not so much physically but more "you have to stay at the welcome desk during your shift and can't just hang out in the coffee kiosk or wander around at will" sort of stuff.

Hi Jane: 

This is an interesting question, and something that came across my desk last week. Under 18 yrs must be accompanied by a chaperone at all times.  We do get interest from elderly but when they realize walking is a big part it can be a deterrent. For the few I'll find an area for them - be it playing cards; watching a movie; washing dishes; etc. 

I truly believe when a person wants to volunteer they should. All people are deservant and valuable - to turn away someone who could have an impact another isn't indictive of my profession.  Elizabeth :)
