Overall Program / Price:
IFRE was one of the most affordable volunteering options that I found. The application process was quick and easy and the coordinators were easily accessible via email to answer any questions, to which I had many. I really didn't have many apprehensions entering the program because they kept me very well informed about what to expect.
Accommodations:
If you have never been backpacking through Southeast Asia before then you might find the accommodations a little shocking. There is no hot water, the bathrooms are "wet rooms", and the beds are not that comfortable and a little musty. The host family however is very welcoming and accommodating. Mosquito nets are provided and there are fans in the bedroom. You may have to share a room.
Food:
The food is very carb heavy and not necessarily typical of Sri Lankan food - almost a simplified version. In fact, I found the host family eating a more robust meal from the volunteers. After a week I was exhausted of the white bread for breakfast, which was getting staler and staler as the week progressed. There is also a noticeable lack of protein in the diet with really only lunch reliably having a protein dish - either lentils, fish or tiny pieces of chicken. There is a supermarket within 10 minutes walk where supplies can be purchased for a low cost, including savory baked good for about $.25 that are quite filling and tasty. It was my savior at times.
Volunteer Assignment:
What you get out of the program is highly contingent on the effort you put in. Every morning I would research on the internet a fun lesson plan (the students can range between the age of 7 to 16 so it's important to keep things entertaining or else they lose attention fairly quickly). In contrast some other volunteers arrived unprepared. There is a remarkable difference in the impact preparation made and the students were highly appreciative of it.
There will also be plenty of downtime. Bring a book, a camera and an open mind. The city has a lot to offer and the people are very curious and friendly.
