Distribution And Absolute Grading System

What's On This Page?

University grading policy allows instructors to use a distribution system, an absolute measures system, or a combination of the two for calculating final course letter grades. Each grading system has its advantages and disadvantages. Consult with your Subject/Program Area Coordinator and consider the following information before determining a grading system for your course. The grading system used must appear on the course outline. Be aware that upon request, instructors are required to provide the method that was used to translate final and, where appropriate, term marks into grades. Additionally, be aware that instructors need to be able to show the link between the course objectives and the criteria used for assessment. 

Distribution Grading System 

Under the distribution (or relative) system, a student's final grade is based on their ranking or relative position in the class upon completion of the course. The General Faculties Council (GFC) has specified that distributions are not mandated by the university. Generally speaking the distribution system is inappropriate unless there is a large class where one would expect a normal distribution to occur.

Absolute Grading System 

When using the absolute (criterion-referenced) system, a student's raw score is compared to predetermined standards of performance. In the past, there has been a fixed scale and letter grade descriptors for scoring under this system. When this scale is applied, a student’s final raw score (out of 100) is compared to the preset scale to determine a final letter grade. This scale is not mandated but instructors are encouraged to use it wherever appropriate.

The 4-point Grading Scale - UNDERGRADUATE

The University of Alberta uses a four-point scale, and grades on the scale correspond to a letter grade as indicated in the following table. Final course grades should be submitted as a letter grade. Course grades are not official until they have been approved by the Vice Dean and posted on Bear Tracks. 

It may be helpful to break down the descriptors as you think about a student's achievement in the course.

A+

exceptional performance with respect to course learning objectives; exhibits original, creative thinking and demonstrates a capacity to analyze critically and synthesize information. 

A

excellent performance combined with strong evidence of critical thinking. 

A-

excellent performance with respect to course learning objectives. 

B+

very good achievement of course learning objectives 

B

good to very good achievement of course learning objectives 

B-

good achievement of course learning objectives 

C+

satisfactory to good achievement of course learning objectives 

C

satisfactory achievement of course learning objectives

C-

satisfactory to poor achievement of course learning objectives

D+

poor satisfactory achievement of course learning objectives

D

minimal pass achievement of course learning objectives 

F

does not meet course learning objectives 

According to University’s Grading Policy, all course outlines must describe the process by which the term marks will be translated into a final letter grade for the course. The process must be consistent with the University of Alberta Assessment Policy and accompanying Grading Procedure, found at the University of Alberta Policies and Principles Online (UAPPOL) website. The following is a suggested statement for explaining how final grades will be determined. In the table below, the first three columns are official university policy. The “Additional Descriptive Information” is merely a suggestion. The information in this column may be deleted or changed, and should be tailored to your own course and then further developed in relation to specific assignments.

Sample Statement for Course Outlines

According to the University’s Grading Policy, “Grades reflect judgements of student achievement made by instructors and must correspond to the associated descriptor. These judgements are based on a combination of absolute achievement and relative performance in a class.” In this course, your work will be evaluated using the general grading descriptors established by the University, as well as the more detailed assessment criteria that will be provided for specific assignments. Your grade on each assignment will be in one of three formats: a descriptor (excellent, good, satisfactory, etc.), a letter (A, B, C, etc.), or a number. When necessary, descriptor and letter grades will be converted into numerical equivalents in order to weight them properly and average them into a final course grade. Conversions between descriptors, letters, and numbers will be made in accordance with the University’s grading policy. Your final course grade will be reported as a letter grade. It will not be official until it has been approved by the Vice Dean and posted on Bear Tracks.

Assigning Grades 

According to the grading policy, when an instructor gives a grade of A (A+, A, A-), it should mean the following: “In my professional judgement, the quality of this student’s work is excellent (as opposed to merely good).”  When an instructor gives a grade of B (B+, B, B-), it should mean “In my professional judgement, the quality of this student’s work is good (as opposed to merely satisfactory).”

Excellence is not something that is “average” or “typical”. Therefore, measures of central tendency would not be expected to correspond to excellence. In practical terms for instructors and grade approvers, a median of A+, A, or A- would indicate an unusual or anomalous grading pattern. Similarly, a mean higher than 3.3 would indicate an unusual or anomalous grading pattern.

It is important to put a lot of thought into what defines work as excellent, good, satisfactory, etc. and to communicate the definitions to students as clearly and as transparently as possible (preferably in relation to specific assignments).

It is also important to ensure that grading scales and rubrics do not lock you into giving grades that do not reflect your professional judgment. Grading scales and assessment tools should be used to assist the decision-making process rather than substituting for it. In all cases, grades must reflect the level of student achievement, and they must match the descriptor such that work deemed to be “excellent” will receive a grade of A (A+, A, A-), work deemed to be “good” will receive a grade of B (B+, B, B-), work deemed to be “satisfactory” will receive a grade of C (C+, C, C-), etc.

Assessment tools (rubrics, grading scales, etc.) should not be allowed to override your professional judgment. They should be used as tools that assist you in formulating judgments rather than becoming the “decision maker”. It usually takes a lot of experience, calibration, and perfecting over time for assessment tools to produce accurate determinations of the quality of a student’s work. If reporting grades as numbers and applying a grading scale is forcing you to give grades that don’t accurately reflect your professional judgment, then it might be preferable to report grades as descriptors (“excellent work”, “good work”, etc.).

Given that letter grades are assigned at the end of a course after all requisite assignments and assessments have been considered and weighted, instructors are asked to not promise final grades using “bands of percentages” (e.g., 90-100%) to letter grades (e.g., A+) in their course outlines/syllabi. This practice should be avoided as it (a) sets up expectations for student final letter grades without giving the instructor an opportunity to fully consider all requisite assignments and assessments and (b) is vague and possibly misleading as to whether it reflects norm- and/or criterion-referenced assessment for students. 

Working with a fixed grading scale requires instructors to monitor after they grade each assignment to ensure that grades match up with their professional judgment.  When there is not a close match, measures should be taken to bring the grades into alignment with the professional judgment *before* grades are reported to students.  Monitoring of total grades as they develop throughout the term is also a good idea.

Grades in any course, examination or other academic assessment shall not be mandated on the basis of a curve or historic distribution of student grades. The distribution of grades shall not be predetermined by any system of quotas that requires a certain number or percentage of grades at a particular level.
