Abstract
The number of migrant children attending Czech primary schools has been increasing. A child's level of communicative competence in a second language, i.e. the language of instruction, is expected to play an important role in the child's progress at school and his/her integration into (school) society.
Until 2010, a child's level of communicative competence in Czech was not measured with a professionally developed instrument and as a result there was a lack of information in this area. Thanks to a set of diagnostic tests in Czech developed since 2010, pupils, their parents, teachers and schools, as well as researchers and the general public, can obtain information about migrant children's communicative competence in Czech.
This paper describes the methodology used to develop the diagnostic instrument, notes several difficulties the test designers encountered and discusses possible solutions to these issues.
