An interscholastic unit may be organized by the school where ethnic or minority language instruction cannot be provided due to insufficient number of course participants or lack of qualified teachers. In such a case a headmaster submits a list of enrolled participants to a school governing body obliged to provide interscholastic units with regard to transportation possibilities.

An interscholastic unit consists of min. 3 and max. 20 pupils.
