Why Choose CoGrader?

Why districts pick CoGrader, and what your teachers see the first week.

Faster turnaround on assignments

Grade and return assignments in days, not weeks, so feedback lands while students still remember the work.

Faster Feedback Turnaround

Provide timely, specific feedback that helps students improve their performance.

Integrity & Grading Equity

Keep consistency and fairness with rubrics-based grading, plagiarism and AI detection.

A reliable AI grader for schools saves teachers hours of grading time without trading rubric fidelity, plagiarism detection, or grading consistency. CoGrader is built to hold all three at once.
“Helping teachers grade, but more importantly helping give quality feedback, and putting the power of great feedback into the hands of kids so they have agency to improve.”

Frequently Asked Questions

CoGrader: the AI Teaching Assistant.

Is CoGrader FERPA compliant?

Yes, when implemented under a Data Privacy Agreement. CoGrader is FERPA-compliant by design: student work is processed without third-party model training, encrypted in transit and at rest, and governed by a district-signed DPA. The DPA template is available in our security packet.

Is CoGrader SOC 2 certified?

Yes. CoGrader holds a SOC 2 Type I attestation, conducted by an independent third-party auditor, covering the security, availability, and confidentiality of the platform that processes student work. The attestation letter is available to school and district evaluators under NDA through our security packet request.

Is CoGrader safe for student data?

Yes. CoGrader uses four controls to keep student data safe: encryption in transit and at rest, access restricted through district single sign-on, no use of student work to train third-party models, and an audit trail on every score. All four are enforced under a signed DPA.

How accurate is CoGrader compared to teachers?

CoGrader validates its scores against human teacher scores on standards-aligned rubrics. The methodology, including rubric inventory and inter-rater calibration approach, is available to district evaluators on request. We do not publish accuracy numbers we cannot defend in a board meeting, so we share data scoped to your context under DPA.

How do schools adopt CoGrader at the district level?

Districts adopt CoGrader in three steps. First, your district signs a Data Privacy Agreement and selects a license tier. Second, our team configures single sign-on and SIS rostering through Clever or ClassLink and provisions your admin console. Third, schools are onboarded with white-glove training. Most districts launch within 30 days.

What platforms does CoGrader integrate with?

CoGrader integrates natively with Google Classroom, Canvas LMS, Schoology, Brightspace, and DMAC for Texas assessment data. Single sign-on and SIS rostering work through Clever and ClassLink, the identity providers most K-12 districts already operate. None of these route through third-party middleware, which reduces your IT vendor surface area.

Does CoGrader offer district or site licenses?

Yes. CoGrader offers volume-based licensing for schools and districts. The district tier includes a signed Data Privacy Agreement, single sign-on, SIS rostering through Clever or ClassLink, the district admin console, district-wide rubric library, exportable reporting, and white-glove onboarding. Contact our schools team for a quote sized to your district.

How is CoGrader priced for schools and districts?

CoGrader pricing for schools and districts is based on student headcount. Enrollment determines the license tier, which includes a signed Data Privacy Agreement, single sign-on, SIS rostering through Clever or ClassLink, the district admin console, and white-glove onboarding. Contact our schools team for a quote sized to your enrollment.

What documentation does CoGrader provide for procurement?

CoGrader provides the artifacts most K-12 procurement teams request: a HECVAT response, a Data Privacy Agreement template, the SOC 2 Type I attestation letter, a FERPA and COPPA statement, an AI grading RFP scaffold, and a security and architecture one-pager. The full bundle is available through the security packet request.
