To ensure the content validity of periodic tests follow the testing that is appropriate for the situation with clear answer and scoring methods. You could also implement separate scoring boards.
To ensure that content is valid on tests you have to understand what you are measuring. Without a clear understanding of what you are measuring you could test for the wrong information.
a test must be appropiate to the learning objectives youv'e set and it implies a high stardard performance'''
The answer depends on the type of periodic test. In many cases, periodic tests are standardized or developed at a bureaucratic level and content is developed outside the teacher's control. In these cases, there is nothing the teacher can do to validate the content of an exam. The teacher is merely a proctor.
A table of specification helps ensure content validity of tests by specifying the proportion of test questions that cover each content domain or skill being assessed. By outlining the distribution of topics or skills tested, the table of specification helps ensure that the test assesses all relevant content areas or learning objectives, improving the content validity of the test.

Content validity is most often used in the development and evaluation of psychological tests, educational assessments, and surveys. It assesses whether a test adequately represents the construct it aims to measure by evaluating the relevance and comprehensiveness of its content. Content validity is typically established through expert judgment and qualitative analysis rather than through statistical methods.
Two common methods for assessing validity in psychological tests are content validity, which involves examining whether the test adequately covers the content it is supposed to measure, and criterion validity, which looks at how well a test predicts or correlates with an external criterion. Other types of validity include construct validity, which assesses whether the test measures the theoretical construct it claims to measure, and face validity, which considers if the test appears to measure what it intends to measure.
To ensure validity of test, one should prepare a table of specification to describe the topics to be covered in a test and the number of items or points which will be associated with each topic and to identify the achievement domains being measured and to ensure that a fair and representative sample of questions appear on the test.
