EMT11..,The local ALS ambulance service I deal with on calls has a couple EMTs who are Intermediates instead of Basics, but they literally do the same job as the EMT-Basics and get paid the same. Their Intermediate certification is pretty much useless. On calls Ive never seen them do anything a Basic doesnt do. There is always a Paramedic with them doing the ALS stuff, Ive never seen an Intermediate with a Basic on an ALS rig, I was under the impression a Paramedic was required for it to be ALS. This isnt GA though, so maybe it varies by state.
Also the school up here that ran an intermediate course had EMT-Basic as a pre requisite. It was a 2 month course to get your Intermediate, whereas basic was 5 months. One of the Intermdiates I just talked to is starting Paramedic school, but he has to start from scratch along with the Basics in his class, the other one is simply going to go back to being a basic, since EMS is just a side job for him anyway since he works as a radiology tech.
