As with any program or idea- there are pros and cons.
Parents and educators should explain what the rules (i.e. no collecting after it gets dark, during davening…) are and they have to be followed, or they won’t be allowed to volunteer.
One organization I volunteered for (as a 13 year old) had a rule that if someone demands the money- no matter how small the perpetrator is and no matter how much money we collected- we have to give them everything.
