"Ersatzschulen" are ordinary primary or secondary schools which are run by private individuals, private organizations or religious groups. These schools offer the same types of diplomas as in public schools. However, Ersatzschulen, like their state-run counterparts, are subjected to basic government standards, such as the minimum required qualifications of teachers and pay grades. An Ersatzschule must have at least the same academic standards as those of a state school and Article 7, Paragraph 4 of the Grundgesetz, allows to forbid the segregation of pupils according to socioeconomic status (the so-called "Sonderungsverbot"). Therefore, most Ersatzschulen have very low tuition fees compared to those in most other Western European countries; scholarships are also often available. However, it is not possible to finance these schools with such low tuition fees: accordingly all German Ersatzschulen are subsidised with public funds.
