In 1986 Shulman developed a typology of teachers’ professional knowledge. Since this, research onteachers’ professional knowledge, especially on the measurement of professional knowledge, hasincreased. Measuring teachers’ professional knowledge requires tests which focus on specific knowledgetypes and subjects. However, there are only few professional knowledge tests analysing teachers’pedagogical content knowledge of using models and chemistry language in chemistry classes.The following article describes the development of a pedagogical content knowledge test for chemistryteachers, which focuses on teachers’ pedagogical content knowledge regarding the handling ofmodels and chemistry language. As a result the test measures the intended construct reliably.
