The prescriptive curricula indicate the evaluation standards on the one hand and on the other demand the teacher's evaluation of general and Niss competences for the secondary education stage.
Objective evaluation is to look in to the content of a mathematics course whether it meets the objective of the course it intends to achieve in a particular field and at a particular level, indicating level of complexities, relevance and degree of abstractness. Evaluation of competencies on the other hand is geared towards the people involved in the course, either students or professors who intend to teach.
The question you now leave to me is: how do you carry out, with your words, "observe the content of a mathematics course, whether it meets the objective of the course you intend to achieve", with what system of categories or referents?
