The accurate statements about grades are:
- Grades help indicate how well a student is understanding a certain subject.
- Students may be required to maintain good grades to participate in certain after-school activities.
- Colleges and employers may judge students’ potential based on their grades.
- Grades are indicators of whether a student is following rules and other expectations.
The statement "Employers look at new employees’ report cards to determine how much to pay them." is not typically accurate, as most employers focus more on skills, experience, and interviews rather than student report cards when determining pay for new employees.
