I thought the UCLA program was great. I went to it last year as a private (non-Fire) student, so most of the instructors I had are probably still there. The lead instructor is a former ground and flight paramedic from Illinois, program director worked on a ground ambulance and as a medic at a small community hospital in Colorado, and most of the instructors are current LAFD medics or work for AMR in San Bernardino or Riverside. All of the instructors are medics. Didactic was engaging and in depth - Wheeler, the lead lecturer, was as interesting a professor I ever had in 4 years of college. He and the other lectureres went in-depth into the pathophys and treatment for real patients commonly and uncommonly encountered in the field and I can still vividly recall some of the lectures (in contrast to one of the above posts that called one of the programs "death by powerpoint"). We had a full cadaver lab as part of the initial A&P unit. The testing was rigorous and high stakes with failing out a real possibility if you scored less than 80% on 2 block exams or 10 daily quizzes.
People like to trash talk LA County prehospital medicine for its limited scope of practice, pretty universally short transport times, and other critiques that I don't really agree with. The program taught and tested a national registry scope of practice, even despite the groans from some LACo firemen who lamented the fact that they'd never need to know some of the stuff since it'd been taken out of their scope. I had busy internship shifts, treated a lot of critical patients. Got tubes, ROSC, got to pace and needle-T, treated anaphylaxis, breathers, overdoses, suicides, homicides, hypoglycemia, strokes, STEMI, seizures, sepsis, MVAs, pedestrians struck, auto vs. bicyclists thrown, GSWs and stabbings. My clinical rotations started on time and there were ample shifts available to schedule as it was practical to me. I got to rotate through busy emergency rooms and every kind of specialty center, got paired up with cool anesthesiologists in my OR rotations who actually let me intubate - it blows my mind when some people say they only get to observe in the OR. My internship started on time as well, and the school facilitated the whole process without putting it on me to find a preceptor.
I've talked to other medics whose programs dragged on for *well* over a year due to gaps between didactic, clinicals and internship, and that astounded me. The UCLA program lasted just over 9 months. It was essentially full time - 36 hours most weeks 0800-1700 Mon/Tues/Thurs/Fri and sometimes Wednesdays during didactic. Clinicals lasted 5 weeks or so, and internship was 20-30 24 hour shifts (2-3 months) with one of the ALS fire ambulances in the county. It was expensive - over $12,000 from the deposit to getting my CA EMT-P card after everything including books, uniform, tuition, and testing fees. I basically went for broke and spent all my savings making it through that year, but I feel it was totally worth it. I totally recommend it. There's limited spots for private students, and its a requirement that you take their paramedic prep program, but I applied once and got lucky that the next session had 9 or 10 private students.
