Mathematical tasks in tests are central to students’ learning.Research shows that there is a significant gap between mathematical tasks in national tests and teacher-made tests.In this pilot study we examineeighteenSwedish and Chinese teachers’ viewsonwhat constitutes of a good mathematicaltesttaskat thelowersecondary school level. E-Mail Interviewing is conducted by presenting sevenmathematical tasks from national tests inSweden and China, respectively. The preliminary results show that Swedish and Chinese teachers hold some common viewsonthecharacteristics of good mathematical test tasks, but they also show different viewson the cognitively demanding tasks. Implications of the results and the methodology informed by the pilot study are discussed.
