Note About Phase II of the training. The second course is an "internship" performed for at least 180 days at one of the major USAF Hospitals. The following information was provided by AXOLOTL1, a member of our Message Forum:

Unless things have changed drastically in the last couple of years, there are only about 11 sites in the Air Force where a Medical Laboratory Apprentice can attend Phase II training. Most of these are at fairly large medical treatment facilities like Wilford Hall Medical Center at Lackland AFB, TX, or Keesler Medical Center at Keesler AFB, MS. Off the top of my head, I think the Phase II locations are: Lackland AFB and Sheppard AFB in TX, Keesler AFB in MS, Scott AFB in IL, Andrews AFB in MD, Travis AFB in CA, Wright-Patterson AFB in OH, Hill AFB in UT, Tinker AFB in OK, the Air Force Academy in CO, and Eglin AFB in FL.

Each Phase II training site can accept only a certain number of students. Lackland and Keesler accept the largest numbers of students by far so you have a pretty good chance of going to Phase II at one of those. The others range from about 20 students down to 3 students in the training pipeline at any given time. If a training site has all of its training slots filled, that Phase II site will probably not be offered to you as one of your choices.

Further shrinking the pool of available sites is the fact that National Guard and Reservist trainees usually get priority for training at the bases closest to where their home unit is. Cross-training active duty members also get to pick from the available training sites before they are offered to members in initial skill training.

It's possible that the top five students in each class might get to choose where they want to go, but it's more likely that they just get first pick of whatever is left after everyone else is done. I'm also very sure that only bases with a Phase II laboratory training program are available for selection, so just let any dreams of training at Hickam AFB, HI go right now.

I attended the Medical Laboratory apprentice course over seven years ago. I graduated first in my class of 21 students, and the cross-trainees did not pick from the list of available training sites like the rest of us. The bases available to the 14 initial training students were Scott, Lackland, Sheppard, Keesler, and the Air Force Academy. As the highest scoring student, I got to pick first from those limited choices, and the lowest scoring airman had to accompany me. The second highest scoring student chose next, and the 2nd to last airman accompanied him. etc...etc until all the students had been placed. Most of the slots (6) were at Lackland, so that's where the middle students went.
