Final answer:
Norman is practicing standardization in his testing method, which ensures fairness and consistency in the administration, scoring, and interpretation of test results.
Step-by-step explanation:
Norman is administering tests for a group of students in different classes. In each class, he gives the students the same instructions and the same amount of time, and he uses the same rubric for grading. Norman is exhibiting standardization in administering the tests. This method of testing is crucial as it ensures that the administration, scoring, and interpretation of results are consistent across all students and classes. This practice aligns with the concept of norms and represents a fair approach in educational assessment, where every student is given an equal opportunity to perform under similar conditions. This ensures that the test conditions are uniform for all students, allowing for fair and accurate assessments.
