The commitment is flexible based on your need. You can cancel at any time. Ideally, we would like you to support your student all the way through until they graduate from our high school program. So how long depends entirely on how old your student is at the time you sign-up to sponsor them. The average age of a student graduating secondary school often is the same as students in the USA, but sometimes students can be older as graduating and progressing in school is based on your performance and not just your age.
