If this is the Tulare County in CA, then they do not do EMS. There are a small handful of smaller private ambulance companies that provide a mix of 911 and Transfer services to the county.
Most if not all of the services operate on an EMT/Medic system for ALS units. I imagine standard EMT minimum requirements will apply.
If the position is with Tulare County Fire, well, don't quit your day job. Entry level positions with TCFD is all Extra-Help meaning you are limited to the number of hours you can work. Additionally, their firefighters are on-call PCFs who make $9/hr while responding to or assigned to a call; and you will generally respond from him with gear in your personal vehicle. The stations are staffed with one engineer or captain at a time, who will handle medical aids. Extra-Help Firefighters are encouraged to have First Aid and CPR training. EMT is a plus. No academy required, they will train you...eventually.
