A school voucher, also called an education voucher in a voucher system, is a certificate of government funding for students at schools chosen by themselves or their parents. Funding is usually for a particular year, term, or semester. In some countries, states, or local jurisdictions, the voucher can be used to cover or reimburse home schooling expenses. In some countries, vouchers only exist for tuition at private schools.

A private school is a school not administered or funded by the government, unlike a public school.
