1. Do you want someone who is Certified?
Having a certified CPS technician is obviously the best choice. Certified CPS technicians must also keep up with continuing education credits and participate in other activities to keep up to date on changes, laws, etc.
So just because someone is certified does not always mean it is time to choose. Someone might have been certified for years, but if they are not up-to-date on recommendations and practice is a safety issue. So there is more to determine the best choice.
