I require students I take abroad to apply to go on the trip through ME (and I may or may not approve them), not just through the travel company (for whom the "application" is just a formality, and anyone who pays the money can go).
This zip file includes the following :
1. Student application (with YOU, the leader)
2. Parent recommendation (for their student)
3. Teacher recommendation (for the student to travel with you)
4. Information about how/why I use the applications/recommendations
*All are fully-editable Word docs.
