How do teachers use standardized test scores?

Teachers need various types of test information as a guide in determining what students know, and what educational problems students have, and how they can be helped. Comparative student data provide valuable information on how well standards are being met.

Are standardized test scores the best measure of student learning?

What does scaling grades mean?

Scaling grades creates new values for assignments relative to each other and the total value of all assignments in the class. These relative values are reflected in the total percentage and final grades only. The grade book will now display grades based on the new scaled values entered by the instructor.

What is a student score?

The student score is the likelihood that a student will be able to answer an average difficulty level question correctly, expressed as a percentage out of 100 (where 50% is the average). E.g. Sam has a score of 57.8 in English, therefore he has a 57.8% chance of getting an average-difficulty English question correct.

How are test grades weighted?

For example, a teacher may choose to make the results of an exam worth 50 percent of a student's total class grade, while assignments account for 25 percent and participation marks are worth another 25 percent. Weighted grades refer to the different levels of importance a professor may assign to certain classwork.
