I will give you my thoughts on Peace Corps. (Although it is important to remember that every country/program is very different and what I say could be right on target with what your experience could be, or it could be far from it) Also, each volunteer is placed with a different agency/community so their experiences are all very different also. I loved my time, but many hated it too.)
Well your placed in a developing country far from anything you could ever imagine. We landed at night, and although it was June there was snow on the ground, and we were immediately sent far from the capital to the northern provincial city, where we were placed in small towns (usually 4 to 6 other volunteers placed in the same town) We lived with families who didnt speak English, and we had yet to learn the local language. I remember hiding in my room overwhelmed, and thinking how the hell did I let myself get into this.
First three months: non-stop training: language, culture, learning about the health system, and major health risks, security training: aka: How to fight off rapid dogs, drunks/stalkers, etc etc.
After that: You are placed in the community that you will live in for the next 2 years.
While some volunteers told Peace Corps to place them were they can be best suited, I straight out asked to live in the capital, and that I wanted to work in certain areas, and that was what I was given. In my program, I full heartedly believe this is what you had to do. My program had already decided the 55 spots where we would go, and then they slotted us into these positions. The volunteers who stated where they wanted, were placed where they wanted, the ones that said place me where I can be best utilized were given the left over spots. Aka: the barren dessert, or the barren steppe. Many of the placements were decided politically. Peace Corps wanted good relationships with certain agencies, etc. Or; one example: Peace Corps wanted the use of a school in the second largest city for summer training, so offered a volunteer in return for the use of the school rent free, or someone is friends with someone so they gave them a volunteer, (and let their friend hand pick which volunteer they wanted)
The Experience: I loved my time there: There were times that I was on the verge of a breakdown, and times that I was on top of the world. I cant name one person in my program who didnt have some type of breakdown/depression as some point in their service. (mine came about 7 months into the experience, coincided with the 50 F winter)
The Work: I was lucky because I was placed with an International Agency that was doing grass roots style work: Therefore I had the cash support, the name recognition, but still working at the grass roots level. Other volunteers where placed with local hospitals, etc, where their was absolutely no money, no resources, etc etc, while others where placed in larger policy style agencies (WHO, UNFPA etc) These volunteers ended up being glorified translators.
My work: I worked within poor slums of the capital, training doctors on confidentiality, teaching male community volunteers: police officers, taxi/bus drivers, miners, construction workers etc on being HIV/AIDS, sexual health peer educators, implemented teenage boys life skills clubs, leadership summer camps. Worked with local schools on introducing healthy lunches, implemented community health campaigns, trained community volunteers on general health, and social work techniques, lead fathers support groups, worked with National Aids Foundation on their internal evaluation report, worked with prisoners, and military regarding sexual health, trained teachers how to apply florid to children within the orphanages, raised money to create several green houses that were used to supplement diet, and create income. That is the tip of my work experience. But again, mine was very different than others: I was lucky to be placed with an agency with money, and who had lots of faith in me, and in a country that is relatively isolated from the world.
