• Grade assignments and examinations consistently, especially in large classes and with handwritten materials.
  • Verify student learning and assess problem areas.
  • Provide students with clear feedback on their work.


Gradescope is a cloud-based platform that allows students to submit their digitized assessments, which can then be associated with a rubric and graded quickly and consistently, including providing standard comments for common issues. Afterwards students can view the scoring and comments, and instructors can view statistics for all rubric items to see which ones gave students the most difficulty. The instructor can also export grades into the Moodle gradebook.

Smartphone apps such as Notes and Scannable for iPhone and Genius Scan for Android allow students to photograph handwritten pages and assemble them into single PDFs for easy upload to Gradescope.

Many courses have assessments whose responses can be graded in a standard way using a rubric describing the basis for assigning credit. Ensuring consistent application of a rubric can be challenging in larger courses, especially when it must be changed mid-stream to account for unforeseen variations. In addition, the comments that one applies to explain loss of credit are often commonplace and writing them multiple times can be time-consuming. Gradescope is a cloud-based application that lets you apply rubrics consistently and provide standard comments quickly, along with automatic adjustments when a rubric is updated.

Gradescope’s basic requirement is that the assessments must be digitized, specifically in the form of a PDF document, so that they can be uploaded to the Web site for side-by-side application of the rubric. This is not a problem for assessments that are “born digital” such as Word documents, but much of the content in academia is still easier to implement in handwritten form. From Chinese and Japanese ideograms to musical scores, from chemical structures to physical force and motion diagrams, paper is still a common medium of expression, and will continue to be so until high-resolution tablet computers with digital pens are commonplace. However, most students nowadays do have smartphones, which have apps available that will not only photograph documents, but also automatically assemble multiple images into a single PDF. Paper assignments can also be collected and run through a scanner. Whatever the origin of the students’ digitized assessments, Gradescope lets you associate their responses with particular questions and rubrics, and then grade each question in turn across all submissions.

Mathematics is the handwritten material with which we are all familiar, so it may not be a surprise that this and other scientific disciplines have led the way in using Gradescope. Math professor Nathan Pflueger had used Gradescope in his previous position, and brought it to the attention of his colleagues when he arrived at Amherst. Within a few years, most of the Department of Mathematics and Statistics was using it, along with several faculty from Physics, Chemistry, and Computer Science.

The image below, provided by Prof. Plueger, shows the basic layout of Gradescope:

  • On the left side, an exam designed to be printed and answers provided in specific areas (though blank paper can also be used);
  • The grading rubric on the right side;
  • The response area that is drawn out and linked to its corresponding rubric (which can be adjusted for individual variations).

Recognizing the beginning of widespread use of Gradescope, IT purchased a site license at the beginning of 2020 — just in time to help absorb a wave of student assignments and examinations turned in remotely due to the COVID-19 pandemic. Academic Technology Services has since taken the lead in introducing Gradescope to other faculty and helping them implement it, including its Moodle interface. It’s now also being used in Astronomy, Biology, Economics, Geology, and Philosophy, and some of the language departments have also expressed interest.

One barrier to Gradescope’s use is the setup time involved, which may not be worth the effort for a smaller class. Another concern is that students may have difficulty with scanning and turning in their assessments, but faculty have not found that to be an issue, generally speaking.

Gradescope has also been a useful tool in courses using graders (again, mostly in the natural sciences), by allowing the professors to review the rubrics used by their graders and if necessary make changes that are immediately applied. An additional benefit is that having a copy of student work prevents subsequent modifications to attempt a regrade. All in all, faculty find that Gradescope ensures more consistent grading, provides better student feedback, and saves them time.
