SAGrader is a learning tool that engages your students with interactive writing activities guided by immediate, personalized feedback.
Unlike other automated essay grading tools, SAGrader is built for low-stakes writing in content area courses such as biology, psychology, business, and history. It works best for high school and college students. Every SAGrader writing assignment is designed to guide students to an accurate understanding of specific content knowledge. For example, in a biology class SAGrader can see how well students understand the process of photosynthesis or determine how well they know the difference between plant and animal cells. Our goal? To promote deep content understanding in content area classes by making writing assignments more convenient.

How It Works
Students are scored based on an answer key created by a subject matter expert.
An expert builds the answer key
For each assignment, a subject matter expert creates an outline of the correct content knowledge. For example, here's a very simple science assignment about the Earth.
- part of the Milky Way Galaxy
- between two other planets:
- Venus (the hottest planet)
- Mars (red color)
- contains 21% free oxygen
We build the semantic network
We add this outline to SAGrader, where it is represented as a semantic network of concepts and relationships.
SAGrader analyzes student submissions
When a student submits, SAGrader uses several artificial intelligence strategies to measure the student's ability to accurately identify, explain and organize the required knowledge. This goes well beyond keyword recognition. SAGrader can model hundreds or even thousands of ways students may express a concept, and we also make sure students are correctly explaining the relationships between concepts.
SAGrader checks for:
Concepts / Ideas
Recognizes variations of the same answer.
"protect" = "guard" = "cover" = "watch over"
Students must organize their ideas correctly.
"The retina contains cones and protects the eye."
"The retina has cones. The cornea protects the eye."
Students won't get credit for saying the opposite.
NO CREDIT FOR:
"The iris does not dilate and constrict."
Feedback and Scoring
Assessment is fast, personalized, content-focused, consistent and accurate.
SAGrader improves the writing process by providing immediate feedback to guide revision. Below is an example of the feedback one student received from their psychology assignment on Gestalt psychologists.
SAGrader feedback is:
- Immediate. Students get feedback in just a few seconds.
- Specific and actionable. Students know exactly how they need to improve in future revisions.
- 100% consistent and unbiased. Students are always graded according to the exact same standard.
- Accurate. Studies have shown SAGrader agrees with human scorers 93% - 98% of the time.
- Content-focused. To encourage deep thinking about content knowledge.
- Personalized. No pre-packaged comments.
SAGrader supports writing assignments designed to assess content knowledge.
SAGrader works best for high school or college-level content area classes. If you teach biology, psychology, sociology, business, or history, you're in the right place. SAGrader emphasizes the assessment of content knowledge. It's great for homework assignments that check for students' knowledge and understanding of your course content. It doesn't work as well evaluating general writing skills, creative writing, or persuasive skills. Use SAGrader for short answer questions, term papers and anything in-between. Writing activities can cover a range of cognitive levels from factual recall and analysis to interpretation and argument.
SAGrader is great for:
- A short answer question that asks students to describe the parts of a plant cell.
- An essay describing the contributions of Sigmund Freud.
- An essay outlining each branch of government and its primary function.
But not a good fit for:
- A persuasive essay about the death penalty.
- An essay you want to evaluate using 6-trait writing.
- A short story about the student's earliest childhood memory.
Assignments that work well in SAGrader
The following examples are actual SAGrader writing prompts taken from a variety of disciplines. These prompts demonstrate just some of the types of assignments SAGrader can handle well.
- U.S. Government (The Fed)
- Describe the structure and function of the U.S. Federal Reserve. What is its most important function? Why have some people called it 'the most powerful branch of government'?
- Sociology (Social Deviance)
- Read the following description of Warren's life. Identify 6 social deviance concepts that are illustrated in the story. For each concept that you identify, provide a definition and quote the passage of the text that illustrates that concept.
- Psychology (REM sleep)
- Discuss in detail the characteristics of REM sleep. Identify both the neurological and physiological effects caused by REM sleep. Describe the stages of the sleep cycle that occur before REM sleep. What distinguishes REM sleep from othe sleep stages?

Frequently Asked Questions (FAQ)
Answers to the most commonly asked inquiries.
SAGrader focuses on assessing the content of students' writing, but you can also add metrics to your assignments that evaluate general writing skills. These metrics evaluate things like spelling, grammar, reading ease and word count. It's worth noting these metrics are currently experimental, which means we're still ironing out some rough edges.
Generally, if you teach a college course, students will pay for SAGrader as a course supplement. There's no charge for instructors. We can work with your bookstore to sell enrollment codes through them, or students can pay us directly online. We can also work out payment from your school or department, but we still charge per student.
High school classes are a bit more complicated since you generally cannot charge students directly. We charge per student, but we can arrange payment from you or your school in whatever manner works for you.
Most other essay grading programs base their scoring and feedback on statistical models of human-graded papers. This allows them to provide fairly generic advice across broad dimensions, like style or focus.
In contrast, SAGrader uses linguistic strategies like Natural Language Processing (NLP) to assess the specific ideas discussed in a submission. This enables us to deliver incredibly specific, topic-based suggestions for improvement. As a result, SAGrader is the only program ideally suited for content area classes concerned with teaching students substantive content through writing assignments.

SAGrader is not useful for grading broadly defined essays with no specific content focus. SAGrader is designed to assess a student's knowledge about a substantive topic as expressed in a specific writing assignment. In other words, we don't recommend using SAGrader in a creative writing class or to assess general writing skills in an English class.
