Only recently has the US Dept of Justice attempted to really put forth any criteria. The National Institute of Justice (NIJ) put out a report in June 2004 sort of outlining basic criteria for Forensic Scientists and their formal training. From the pdf.: "Forensic pathologists.........are licensed physicians who have completed medical school, 5 years of pathology internship and residency, and 1 year of forensic pathology fellowship....."
May I ask why you're taking chemistry courses instead of biology for this track? Do you have a good advisor who's knowledgeable on this subject? Do you have a specific undergrad track at your school, or is this a do-it-yourself type thing you're putting together? The reason I ask, is because, it's a fairly new idea for some colleges to be offering an actual forensics degree. My school will be starting their charter class this fall (to which I have an acceptance, BTW)
I'll tell you what's on MY degree plan: since toxicology is my main interest, and I have already done all my backelor's work for biology, I will essentially be earning a BS in chemistry, plus a certification. To get the certification, I have to take classes in criminalistics, criminal investigation, forenseic microscopy, forensic biology, medicinal chemistry, among others, an internship at various crime labs around this area, AND pass the exam. The certification is given by the AAFS (American Academy of Forensic Sciences), whose website I will link below. WHen you visit the website, look on the left for the pdf. from the NIJ that I quoted above. It will tell you what the academy is looking for as far as standards for forensic scientists, as well as classes you should be taking. Also, look under "becoming a member" and look under the pathology section. There are e-mail addresses for the heads of each specialty. I bet you could glean a lot of good info from them. Unfortunately, you can't get onto the discussion forums without a membership, but a student membership is only $55, with a $15 app fee. I highly recommend it. I'm in the process of applying now. I think there's a bunch of flase information and disorganization out there, because of CSI and TV, and it's such a growing interest that the schools are scrambling and trying to get programs into place. This report by the NIJ only came out this past summer, if that tells you anything. Good luck to you. I'm lucky in that I go to a school that has an awesome Forensic Ph.D on faculty.
