Effective Grading StrategiesAssigning grades is one of the most important tasks of college teaching. The high stakes of students' grades combined with the challenge of devising a grading system in which final course grades reflect the desired students' performance makes effective grading very difficult. A grading system should fairly and accurately differentiate between different levels of student performance. In addition, a good grading system must be understood by all students and must allow students to monitor their own progress throughout the term. A course grade is a certification of competence; thus, it is important that each grade accurately reflects a student's mastery of course material. Effective grades provide a stable indication of how well students understand course material, so factors used to determine grades should be directly related to academic performance. With this in mind, instructors need to carefully examine how grades are calculated; factors such as effort, participation, attendance, or extra credit should not be included in the final course grade as they may contaminate the accuracy of a grade. In general, instructors are encouraged to integrate other forms of feedback (verbal praise, student conferences, written feedback, etc) to motivate student performance and avoid using grades as incentive for behaviors such as attendance, discussion, etc. To facilitate students' success in your course, your grading system should be clearly communicated in writing at the beginning of the term. Students should understand how grades will be determined, what factors are used to calculate grades, and what level of performance is required to achieve each grade level. A clear grading structure will guide student performance while reducing the number of grade disputes and student complaints.

|
Advantages |
Disadvantages |
|
Reduces competition among students |
Cut-off points may not effectively represent desired performance |
|
Provides clear goal and set of expectations |
Needs to be based on reliable and valid assessments |
|
Useful for tasks requiring cooperation between students |
May not be fair for extremely difficult assessments |
|
Promotes the use of specific, measurable learning objectives |
May not take into account the cognitive complexity of tasks |
|
Students grades not influenced by the quality or caliber of the class |
Not effective for providing a detailed differentiation between students |
|
Provides motivation for all students |
May not meet institutional demands for a standard grade distribution |
|
Generally preferred by students as they can easily monitor their own progress in the course |
|
|
Provides a consistent indicator of what students have learned from term to term |
|
|
Selects students with a certain level of competence |
|
Generally, criterion-referenced grades are based on a fixed numeric scale. The numeric scale is then converted into either percentages or letter grades to conform to standard academic grading. For example:
| Grade | Points |
Percentage |
|
A |
95-100 |
90-100% |
|
B |
85-95 |
80-90% |
|
C |
75-85 |
70-80% |
|
D |
65-75 |
60-70% |
|
F |
less than 65 |
-60% |
Variations:
Hierarchical grading - In hierarchical grading, the instructor lists specific learning objectives that must be met to achieve each grade level. Each successive grade level requires a greater degree of student understanding or more advanced skill level.
Contract grading - To utilizing contract grading, the instructor must first list all relevant course activities and specify a number of points that may be earned for completing each activity. Students then complete the activities that will earn them enough points to achieve the desired grade.
Pass-fail grading - A pass-fail grading system sets a specific criteria that must be met to pass the course, but there is no differentiation of grades beyond the passing standard. Generally, a pass-fail system is utilized when the grading is very subjective and there is no standard gradation.
Norm-referenced
In a norm-referenced system (also called relative or curve grading), grades are based on studentsÂ' performance in relation to each other. Norm-referenced grading relies on a standard score distribution in which there is a predetermined number of students receiving each grade level. As such, students are in competition with each other to earn the predetermined grade slots. Generally, norm-referenced grading is utilized when the purpose of grading is to screen out or identify the best students within a specific cohort (such as graduate school admission or job placement).
| Advantages | Disadvantages |
|
Allows instructor to differentiate between students |
Promotes competition between students |
|
Corrects for assessment and/or instructional error |
Grade may be influenced by caliber of class or other students |
|
Easy for instructors to use |
Grades cannot be compared from one term to another |
|
Consistently provides a standard distribution of scores |
May not be fair for small classes |
|
|
Difficult for students to monitor their progress in a course |
|
|
May reduce the motivation of lower achieving students |
|
|
Does not provide information on students mastery of course material |
Norm-referenced grading systems are based on a preset distribution of scores. For example:
| Grade | Rank in class |
|
A |
= top 10% |
|
B |
= next 20% |
|
C |
= next 30% |
|
D |
= next 20% |
|
F |
= bottom 20% |
Variations:
Anchoring - Anchoring allows instructors to reduce the influence of class caliber by adjusting grades in relation to a known standard of performance. When using anchoring, instructors modify the distribution of scores based on past experience or external standards.
Ideas to improve the relationship between learning and grades:
Weighted assignments - To give credit for acquisition of knowledge or skills, you may want assignments at the end of the term to count more toward the final grade than assignments completed at the beginning of the term.
Redo assignments - Allowing students to earn credit for redo assignments promotes the use of feedback and encourages students to truly learn course material.
Multiple test opportunities - Giving students the opportunity to retake a different version of an exam allows you to monitor whether or not students have mastered material. If the goal is to promote learning, students should not be penalized for learning information at a slower rate than other students in the course.
Assignment challenges - Permit students to challenge questions or items that they feel are unfair assessments of their knowledge. Provide credit if a student is able to effectively demonstrate their understanding.
