The "Mittelschule" is a school in some States of Germany that offers regular classes and remedial classes but no college preparatory classes. In some States of Germany, the Hauptschule does not exist, and any student who has not been accepted by another school has to attend the Mittelschule. Students may be awarded the Hauptschulabschluss or the Mittlere Reife but not the Abitur.
