An a teacher have test with content validity even without making TOS?

No, a teacher cannot definitively claim a test has content validity without creating a Table of Specifications (TOS). While a teacher might *believe* their test covers the relevant material, a TOS is the crucial documentation that proves it systematically.

Content validity refers to how well the test items represent the entire domain of knowledge or skills being assessed. A TOS explicitly maps the test items to the specific learning objectives and content areas covered in the curriculum. Without this mapping, it's impossible to objectively demonstrate that the test comprehensively assesses the intended content and avoids biases or omissions. The teacher's judgment alone is insufficient for establishing content validity.
