Does the result of periodical test reflect evaluation of a curriculum?

The result gathered from a periodical test does reflect towards the evaluation of a curriculum in terms of being able to reassess its effectiveness in the student's performance. In theory, a set of subjects within a given curriculum should be easily learned by the students. There has to be something wrong when the results from a periodical examination come back with a high percentage of failures. The students can be blamed to a certain degree but isn’t it the job of the school to gain most if not all of the learner's interest. It is up to the establishment’s thinkers to design, adjust, and readjust techniques to provide the best learning tools, in terms of environment, activities, and curriculum. If most of the learners constantly fail in their periodical exams, then maybe it’s time to look for adjustments in the way things are done.
