The French government highly subsidises private elementary and secondary schools, even those affiliated with religious organizations, as long as they apply the same curriculum as the public schools, with the same academic standards, and that they do not discriminate on grounds of religious affiliation nor make religious education compulsory. It is for instance common that children of agnostic or otherwise non-religious families, or children of families from other religions, are put in Catholic schools, if their parents judge these schools to offer better conditions of education or to be more convenient. Consequently, families can use private schools at moderate costs. While there are no accessible official national statistics on the costs of private schools, typical prices per year for low-income families are in the range of a few hundred euros. The average costs are €500 a year per student; however, this statistic includes very expensive, exclusive schools. In addition, according to the figures from the secretariat, more than half of schools have established a price schedule taking into account a family's income; as a result, costs to parents can be as little as €20 to €30 per school month per student.
