I volunteered with World Camp in 2006 and on and off again from 2008 to 2010. My experience, like every one else I have come across, was amazing. World Camp is well established in Malawi and has relationships with the schools, teachers and kids they work with. This partnership goes a long way towards making their work effective. They're not just an organization that drops in to a community for a few days here and there, they have have relationships that go back, they listen to the needs of the specific communities and because of all that, they are well respected by the people with whom they work.
On the volunteer experience, World Camp keeps you busy. If you're looking for a five week vacation in Africa, this probably isn't the right program for you. You'll be challenged daily by the coordinators, the teachers, the kids, the translators and your fellow volunteers to think critically about the work you're doing and how you can be more effective. World Camp listens to its volunteers and if you have ideas about how to make the program better, there is amble opportunity during and after your volunteer session to make those ideas a reality.
It sounds cheesey to say this, but World Camp is a life-changing experience. Volunteering with World Camp affects every individual differently. But it's an experience that will change you and you'll never be able to forget about Malawi and the people you met there. You might even go back or make a living doing the work that World Camp started you on.
