Principles

• Practicality: the task is not expensive, it only takes few minutes to be done and teachers need a score.


• Reliability: it is reliable because it has a score/rubric to be followed.

• Validity
- Content-Related Evidence: the content follows what the students had in class.
- Criterion-Related Evidence: we use criteria to evaluate the students (a rubric)
- Construct-Related Evidence: the task and the book follows the Communicative

Approach.
- Consequential Validity: the students can communicate from what they have learned.
- Face Validity: the directions of the task are very clear.

• Authenticity: It is a real life situation


• Wash back: The effect is positive because the knowledge of the students is not for the test, but for their learning.
