Research · AI Grading
The question of how to integrate artificial intelligence into classroom grading is a nuanced one. Research reveals that AI grading systems offer vast possibilities for improving student outcomes while simultaneously freeing up teacher resources for human-centric tasks. To maximize these benefits, educational technology must be designed to enhance, rather than replace, the essential role of educators.

The Evidence
Full automation can match human graders
A foundational paper by Ferman et al. (2020) investigated the impact of a fully automated evaluation system in the classroom. The study compared two technologies designed to outsource grading and feedback on student writing: one was a “pure” fully automated system, while the other utilized an “enhanced” model backed by human graders.
Interestingly, the field experiment found that human grading added no extra benefit to this specific setup. Student essay outcomes improved significantly in both groups, and the additional input from human graders did not improve the overall effectiveness of the grading. This suggests that automated writing evaluation systems can reliably expand the set of tasks being automated.
Furthermore, instead of reducing teacher involvement, the data shows that reducing the burden of routine tasks actually shifts classroom activities toward nonroutine, personalized human interactions. Both the pure and enhanced automated evaluation systems successfully increased the number of training essays that students directly discussed in person with their teachers. By allowing the AI to absorb the systematic, rule-based labor of processing syntax, grammar, and orthography, teachers can redirect their finite energy toward providing individual support, guidance, and counseling.
LLMs elevate novice graders to expert level
A study by Xiao et al. (2024) discovered that large language model assistance can significantly help human graders improve student outcomes. While LLMs like GPT-4 do not necessarily outperform conventional grading models on their own, they possess high consistency and generalizability.
LLMs can effectively empower novice evaluators and elevate them to the proficiency level of expert graders.
By providing instant feedback and natural language explanations, these tools scaffold the scoring process and improve student learning along the way.
Teacher in the Loop
A partnership, not a replacement.
Platforms like Collage understand the long-standing feedback gap problem that educators have been working through for years. Rather than removing the teacher from the loop, Collage is built to facilitate a partnership, allowing human professional judgment to continuously monitor and adjust the technology.
With Collage, you can change and customize the feedback our model generates for your students at any time. This flexibility ensures that the AI remains adaptive to your specific classroom context, curriculum goals, and student needs, acting as a personal teaching assistant.
Formative Assessment
Three instructional questions AI helps answer
Integrating LLMs into the formative assessment process is most powerful when it addresses the core instructional stages: clarifying where learners are going, assessing where they currently are, and determining how to move them forward.
01
Where learners are going
Clarifying the destination — the concepts and mastery students are working toward.
02
Where they currently are
Assessing each learner’s present understanding in real time.
03
How to move them forward
Determining the next step and providing turn-by-turn guidance to get there.
The Takeaway
Ultimately, AI grades and evaluates much more effectively when it is supporting you, not replacing you. By balancing automated efficiency with human expertise, educators can cultivate deeper student engagement while maintaining absolute pedagogical control.
