Sure - I hope the information was helpful!
I do think there is a good focus in the coursework on interpersonal, two-person psychology techniques and theory. In addition, all of my supervisors so far have focused, at least to some extent, on relational dynamics between therapist and patient. Insight oriented and supportive therapies are also covered really thoroughly.
As for other, non-psychodynamic modalities, i wouldn't say they encourage seeking these opportunities, but it is definitely possible and relatively easy to do so. For your first year of clinical work at GW, you would be placed in the GW on-site clinic, which is (because of the supervisors affiliated with our program) almost always psychodynamic. However, for the second clinical year (third year in the program), a lot of people choose to apply for off-site externships. I chose to do this, and I am currently placed in a site that offers opportunities for clinical work and training using a wider variety of techniques. I really recommend doing that, particularly if you are interested in working with children. There are lots of different kinds of externship sites in the D.C. area. Some of my classmates are doing assessment-only externships; some are using CBT, exclusively, at their sites; some are doing family therapy; and most are doing some kind of mix.
i don't know much about credit transfers, as I came in without a Masters. I'm almost positive that some people were exempt from taking certain required courses because they had taken something similar in a Masters program. It might be done on a course by course basis, depending on how thoroughly the Masters class covers the material in a particular GW class.
Career guidance seems pretty good so far! My advisor loves to give me the names and contact information of former students who are doing the kinds of things I eventually want to be doing. I think the amount of guidance you get probably depends on how much you ask for; they haven't had a lot of formal information sessions (so far), but certain professors are known to be good people to go to for professional development advice.
It sounds like you are interested in working with kids, and should give you a heads up that it can be a challenge to get those kinds of experiences in your second year (third year is much easier, especially if you can get a child-focused externship). I would recommend speaking to the students one year above you for current information on the best affiliate site placements that will give you the kinds of child experience you need. You should also befriend the post-docs, who are in charge of assigning therapy and testing cases in the Clinic. Basically, I've found that I was able to get a lot of different kinds of experiences with children and adolescents, but I kind of had to fight for it.
I am working on my MAP right now, and expecting to be done with it in May. It's not as difficult as it could be, because I completed papers for previous classes that were kind of a precursor to my MAP. As for the topic, the MAP is always a case-based paper that incorporates a lot of relevant literature. Because it's based on a client I worked with, I don't want to reveal too much about my topic in this public forum, but I can give you more information via private message if you would like.
As for biological clock concerns, I know that several people have had babies in the program since I've been there, and many others came into the program with children. To me, it seems like it would be very challenging to balance everything, but I've noticed that the people who do this seem generally calmer and more levelheaded than the rest of us. I think they must have a very clear handle on their priorities. A lot of people who have babies do the four-year plan to give themselves extra time. There are also breaks in the end of the summers, although with comps and clinical work, they aren't usually true breaks. The lightest coursework is definitely during the first year, hands down (mostly because you aren't seeing clients yet) - but I know that some people take extra classes during the first year so that it will be lighter later.
I hope that helps!
