Guidelines for Reducing Implicit Bias in Your Grading

When asked what they most dislike about teaching, many instructors put grading at the top of the list. They find the process time consuming and stressful, topped off by demands from students that their assessments be logically justified. Who hasn’t found themselves in a situation of confronting a student who feels treated unfairly in the grading process and whose persistent questioning reveals that a grade does not stand up to scrutiny. Indeed, upon close inspection, the grading seems arbitrary and hard to defend. What to do?

Grading needs to be done well to give students the feeling that they are being treated fairly in the assessment process. Instructors need to use the same criteria of reliability and validity in designing assessments that they use in their empirical research. Just as they might be called upon by reviewers to defend the quality of data used in an article, so also must they have an answer to students’ queries about the rationale for their marks.

From my perspective, “implicit bias” constitutes a threat to the integrity of the assessment process. Instructors need to take every possible step to reduce the possibility that grades reflect less the merits of the answers than the personal characteristics of the student or the arbitrary whims and fancies of the grading process. Race, class, gender, sexual identity, social capital, and other student characteristics can affect grading if instructors haven’t created a process to limit their effects.

In addition, I believe instructors’ overconfidence in their grading abilities constitutes another form of implicit bias that hampers their ability to assign grades fairly. Keeping the process opaque and not sharing grading criteria with the students emphasizes the unequal power between students and instructors, and is another source of student cynicism about the educational process.

What steps might instructors take?

First, grade all assessments blindly. This means making sure there is no identifying information available while grading the assignment. You can do this by having students turn in blue books with the cover page turned back, by having identification numbers instead of names, by having students fold over the top of the page on which the name is written, and so forth.

Second, prepare an answer key beforehand for all answers. Some instructors call this a “rubric.” The answer key should not be simply bullet points, but rather a fully written out answer, of the kind you would expect to earn full credit on the question. You could also have a list of characteristics or features you’d expect in the question, but the sample answer – – which should be posted or handed out to the students – – should be complete and in prose form.

Preparing the answer ahead of time lets the instructor know that a question can, in fact, be graded. In addition, it prevents “bracket creep” in which an implicit and unwritten template for an answer subtly changes as the instructor reads through the answers and subtly changes the criteria for a grade. If you aren’t certain as to whether your template is too tough, you should read a sample of the answers ahead of time, before grading them, and revise your template if necessary. The rubric should not be changed, once grading is underway.

Third, write out the comments necessary to justify your mark. Don’t just write a simple one or two-word phrase, such as “good job,” or “not complete.” Write enough information next to the answers so that you can explain to students, when they come to you for advice, why you gave that particular mark.

Fourth, grade all of one question before beginning to grade the next question. For example, if your exam consists of four essay questions, you would grade all of question one first, going through all the exams, and then shuffle the exams and grade all of question two. And so on throughout the four questions, in order. This ensures that you are using the same standard throughout your grading and that your grading is not influenced by marks that you have given for previous answers.

You must ensure that a student’ s grade on a previous question is not visible to you. Otherwise, that grade is likely influence the grade you give the current question. Turn over the previous page so that you cannot see it.

Firth, take breaks while grading, and do not attempt to binge on finishing the grading in one sitting. Mistakes are much more likely if you continue grading to the point of exhaustion!

Working to ensure that your assessments are graded reliably and validly requires a bit more preparatory work on an instructor’s part, but the extra work returns huge dividends. When students realize that you are taking great care to grade their work fairly, they take a much more positive view of the assessment process. By the time they get to college, many have become quite cynical about the way instructors exercise their power in handling assessments, and they will appreciate the extra effort you take to make the process as transparent as possible.
