The following study examines the construction of the national tests in history. The study has analyzed the work processes of the construction of the test at different moments, such as design, conduct and evaluation, from the perspective of the test designers and the test manager at the National Agency for Education. The purpose is to see how the test designers’ previous experiences are reflected in the work process with national test and what problems, challenges and limitations they have in their work. The study is based on qualitative interviews and has used the validity theory as an analytical framework. The results show, among other things, that the work process of the national tests begins with the group interpreting the curriculum for history. The interpretation is written down in the so-called construct which is sent to the National Agency for Education for further review. The test designers performed various evaluations of the tests throughout the whole work process. The National Agency for Education conducted a large survey after completing tests that the teachers answer. The results also show different limitations, problems, and challenges of the test design. The framework of the test limits for example the design; what the test should look like, pictures and question construction, it systematizes the test. The processes of the conduction of the test in schools is also completely controlled by the National Agency for Education and the test does not necessarily reflect the teaching that is conducted in the classroom. Another problem is that communication with the active teachers is rather one-sided. Challenges that the test designers face includes setting grade requirements and stable results.
