Top 8 AI Assessment Tools for Teachers to Improve Student Learning

If you’re a teacher looking for an AI assessment tool, you’ve likely either tried one that didn’t match how you assess students or you’re still doing everything manually and running out of time to make a change.

The right tool depends entirely on how you teach, but the problem is that most AI assessment tools are only built for one assessment type. Some can handle a structured short-answer check, while others are built for a final essay. However, most tools can’t do both.

Since there are now hundreds of AI tools available and the differences between them aren’t always obvious, we’ve tried to simplify it for teachers who already feel overwhelmed.

This guide covers 8 AI-powered assessment tools for teachers, starting with CoGrader, our own AI grading tool. We also explain the difference between formative and summative assessments and why it’s so important to consider when choosing an AI tool.

Formative vs. Summative Assessments (+ Why It Matters for the Tool You Choose)

Before getting into the best tools, it’s worth clarifying the difference between formative and summative assessments and why this matters so much when choosing an AI tool.

• Summative assessment is the measurement of learning. That includes the final essay, the end-of-unit test, or the research paper. It occurs after instruction and serves primarily to capture what a student knows or can do at a given point in time.
• Formative assessment is the process of learning. It includes non-graded polls, paragraph checks, draft responses, and mid-unit writing samples. It happens during instruction, and its purpose is to give students (and teachers) information they can still act on.

Typically, summative feedback lands after the learning window has closed. A student who gets a 72 on their final essay with notes about a weak thesis structure can’t go back and fix it. But since formative feedback is returned while the unit is still in progress, changes can still be made.

For writing teachers, this creates a specific problem. Most AI assessment tools are built for one or the other. Some tools handle real-time formative checks well, but they’re designed for multiple-choice and structured responses. Others are built for full essays, and can’t handle short written checks that actually move students forward mid-unit.

That gap matters because in ELA, social studies, AP courses, or any writing-heavy class, your formative checks and summative assessments are the same kind of task at different scales. A paragraph check and a five-page essay both require rubric-aligned, criterion-specific written feedback, just at different stages of learning. A tool that can only do one forces you to compromise on the other.

The AI assessment tools worth using for writing teachers don’t make that tradeoff. They apply the same rubric framework to a two-sentence exit ticket and a full argumentative essay, return results fast enough to inform the next day’s instruction, and highlight class-level patterns so teachers know what to actually do with the data.

This is what separates a grading tool from an instructional one, and it’s how we evaluated the best options worth considering for teachers.

8 Best AI Assessment Tools for Teachers

Below, we cover eight AI assessment tools for teachers. These tools are all built for different stages of the assessment process. Some handle written grading and feedback well, while others focus more on live formative checks, quiz-based practice, or assessment creation. There should be a tool in this guide that fits your teaching style.

1. CoGrader: AI Grading and Feedback for Essays & Written Assessments

CoGrader is an AI grading tool built for teachers who assign a lot of writing. It grades both essays and summative and formative writing assessments faster than any manual approach. Every graded assignment automatically generates a detailed breakdown of class performance, showing exactly which skills students are mastering and where they’re falling short.

Many teachers who have tried to use AI in the classroom have likely experimented with ChatGPT for things like lesson planning, generating feedback for student work, or coming up with assignment questions. While it can be useful, it ends up being more time-consuming to use as a grading tool than doing it manually, and it can’t accurately generate the kind of class-wide performance data that informs your next lesson.

CoGrader is built exclusively around writing assessments, which means every graded essay or paper generates a detailed breakdown of your class’s performance. You can see exactly which rubric criteria students are mastering, where the class is consistently falling short, and which students need targeted support before the next lesson.

For writing teachers in particular, this means you get instant, actionable data on your students’ performance for both formative and summative assessments.

CoGrader grades a short mid-unit paragraph check the same way it grades a full research paper, so you always have a clear, criterion-specific picture of where your class stands at every stage of the writing process. And it takes about 2 minutes to grade your entire class and generate all of this data.

Generate Actionable Student Performance Data Instantly

Teachers who manually grade assignments or use generic AI tools to help with the process typically struggle to get a clear picture of class-wide performance because neither approach generates the kind of structured, rubric-aligned data that tells you how students are performing.

CoGrader generates detailed student performance data automatically the moment grading is complete. You get an immediate breakdown of how your entire class performed, down to the specific skills and criteria where students are excelling or falling behind.

A teacher can look at one chart and immediately see that 19 students did well on argument structure, but 4 are struggling with integrating textual evidence. You know exactly which students need targeted support and can address it directly, instead of reteaching the concept to the entire class.

The dashboard breaks performance down into strengths, areas for growth, reteaching recommendations for struggling students, and enrichment suggestions for students who are ready for the next challenge. You can also create new teaching slides directly in CoGrader based on the results.

There are additional analytics charts you can use, including:

• Student view: Analyze individual performance by rubric criterion to identify exactly which students need targeted support on which specific skills before the next class.
• Formative vs. summative comparisons: Compare scores across drafts to see whether the instruction between a mid-unit check and the final submission moved student performance in the right direction.
• Score distributions: See how performance spreads across the class rather than just the average. This highlights which skills the majority of students are doing well and where a specific assignment is creating a consistent breakdown.

Choose Your Rubric To Grade Against Relevant Criteria

Most AI assessment tools evaluate student writing against an internal model of what a good essay looks like. The problem is that the model has nothing to do with your state standards, your assignment prompt, or how your school expects student work to be evaluated. This usually results in surface-level feedback that doesn’t reflect what you asked students to do.

CoGrader takes a different approach by grading against your specific rubric criteria. Before a single submission gets evaluated, you decide the standard the AI is grading against. This directly impacts student scores, the feedback language, and the specific passages CoGrader flags in each student’s writing.

There are four ways to bring a rubric into CoGrader:

1. Upload the rubric you’re already using. Import your existing rubric as a PDF, image, or document, and CoGrader grades against your criteria without asking you to generate new standards from scratch.
2. Select an existing rubric from the CoGrader library. Our system’s rubric library covers all 50 state standards, AP, IB, and Cambridge A-levels.
3. Generate a rubric from state standards. Enter your state, grade level, and subject, and CoGrader returns a list of standards-aligned options to choose from.
4. Describe what you need and let CoGrader build it. Tell CoGrader the grade level, the text, and the task, such as “9th grade literary analysis essay on The Kite Runner,” and it generates a rubric calibrated to that specific assignment.

Teachers can also manually create a rubric in CoGrader. But writing rubric criteria from scratch can take just as long as manual grading. For most teachers, one of the four options above gets them to the same place in a fraction of the time.

Grade the Whole Class Before the Learning Window Closes

Because manual grading can take so long for teachers to complete, written assignments aren’t really functioning as an assessment anymore. By the time feedback reaches students, they’ve already sat through dozens of class periods across different subjects.

That makes it difficult to remember what they wrote about, connect specific comments to specific choices they made in the draft, and apply that feedback to their next piece of writing.

This is largely because teachers are working through grading loads with unrealistic turnaround times. At 15 to 30 minutes per paper, a teacher with 100 students is looking at 25 to 50 hours of grading for a single written assignment.

CoGrader eliminates those time and workload constraints by grading the entire class against your rubric in approximately 2 minutes.

A class set that would normally take a full weekend can be ready before the next class period, so students get feedback while the assignment is still fresh and have plenty of time to act on it.

CoGrader’s grading process is completed in four steps:

1. Import your class from your LMS. CoGrader allows you to import your class from Google Classroom, Canvas, Schoology, or Brightspace. This automatically syncs your class roster, existing assignments, and student submissions into the system without manual entry or uploads.
2. Set your assignment standards before grading begins. Choose a rubric from your saved library, pull one from CoGrader’s pre-built collection, or generate one based on the specific standard you’re grading against. Add the grade level and any other details so CoGrader knows how to calibrate before it starts grading student submissions.
3. Automatically grade every student submission at once. Rather than working through submissions sequentially, CoGrader processes every student at the same time and generates immediate feedback. Each piece of feedback is tied to specific passages in that student’s writing, rather than generic comments at the top of the page.
4. Manually review and approve each assignment. After grading concludes, submissions must be reviewed by teachers. There is no bulk approval option, so teachers need to read the feedback, make any edits, and sign off individually. This still takes a fraction of the time it would take to grade every assignment manually from start to finish.

Teachers can also adjust the grading parameters if they want to make further changes that are not reflected in the rubric.

Some settings that can be adjusted include:

• Strictness: Slide between tolerant and strict depending on where students are in the writing process. For instance, a first draft and a final submission shouldn’t be graded the same way.
• Reading level: Match the language of the feedback to the students receiving it. Comments written for a sixth grader should read differently than comments written for an AP senior.
• Feedback depth: Choose between concise and thorough depending on how much you want students to digest at once. Sometimes one clear directive is more useful than a full breakdown.
• Tone: Set formal or friendly depending on what actually lands with your class. Both options are educationally valid, but the difference is in knowing your students.

After adjusting those settings, CoGrader applies them consistently so the feedback a student receives reflects both the rubric criteria and the specific context of that assignment.

CoGrader also lets teachers choose how feedback is structured before it reaches students. If your school already uses a specific framework like Glow and Grow or Two Stars and a Wish, CoGrader delivers feedback in that format rather than forcing students to adapt to something unfamiliar every time an assignment comes back.

Every comment is tied to a specific highlighted passage in the student’s writing. This is a more effective approach to grading than leaving generic summaries or comments at the top of the page without a connection to specific passages.

Students can see exactly which sentence or paragraph the feedback refers to, what worked and what needs to be fixed, and what to do differently in the next draft.

Before anything reaches a student, teachers have full editorial control. The built-in chat feature lets you redirect any piece of feedback with a plain-language instruction. Feedback can also be translated for ELL students or adjusted for reading level.

LMS Integrations, AI Detection, & Plagiarism Screening

Any grading tool that requires you to download submissions from one place, upload them somewhere else, and then manually re-enter scores and comments when you’re done hasn’t saved you time. It’s only made the process more difficult and time-consuming.

CoGrader connects natively to Google Classroom, Canvas, Brightspace, and Schoology. When you’re ready to grade, your class roster, your assignment prompt, and every student submission are already there. When you’re done, approved feedback goes back through the same channels without any exporting.

CoGrader also includes both AI detection and plagiarism screening directly inside the grading workflow. Teachers don’t need to switch to a separate tool to check originality before giving feedback.

The AI detection score flags submissions that may have been generated or heavily assisted by AI, while plagiarism screening compares student work against existing sources to surface potential copy-paste issues. Both features are meant to guide review, not replace teacher judgment.

2. Snorkl: Formative feedback on voice responses, diagrams, and math problems

Snorkl is a formative assessment tool that checks what students actually understand by asking them to explain their reasoning. Teachers create a prompt or problem; students respond by recording their voices while working through it on screen; and Snorkl’s AI-driven engine evaluates the reasoning process rather than just the final answer.

For subjects where process matters as much as outcome, like math, science, and any class where showing your thinking is part of the learning, Snorkl captures something a written quiz can’t.

Key features

• Voice + whiteboard recording that captures student reasoning in real time
• AI-generated feedback tied to how the student worked through the problem, not just whether they got it right
• Infinite canvas with no recording time limit
• Teacher dashboard with live progress tracking and the ability to group, sort, and filter responses

5. Formative: Real-time formative checks and live student response tracking

Formative gives teachers visibility into student progress as it happens. It’s an educational tool teachers use to create digital assignments and lesson plans, along with automated grading and feedback.

Formative’s AI can also auto-score short-answer responses against criteria you define, which reduces the manual review burden for open-ended questions. The platform is built around creating interactive learning experiences that give teachers real-time insight into how students are performing before the lesson ends. But when it comes to long-form writing with complex rubric criteria, a dedicated grading tool will serve you better.

Key features

• Real-time student response tracking with live teacher visibility as students type
• Multiple question types, including drawing prompts, uploaded images, and open-ended responses
• AI-assisted auto-scoring for short-answer questions
• Live class controls to pause activity and address patterns in real time
