Core Capabilities

  1. CAPABILITY 01

    Rubrics stay teacher-owned

    Build from your own criteria, start from a template, or reuse the rubric your department already trusts. Assignment snapshots keep existing grades anchored to the rubric version teachers approved.

    • Custom criteria and point scales
    • Reusable across assignments
    • Rubric snapshots protect existing grades

  3. CAPABILITY 03

    AI drafts against the rubric

    The draft output is criterion-level: scores, written justifications, confidence signals, and feedback language that can be inspected before a teacher decides what is accurate.

    • Per-criterion scores and justifications
    • Confidence signals for closer review
    • Drafts are validated before they are shown

    Product preview

    AI draft run

    Review required

    Draft score summary

    AI confidence: medium

    Teacher review is required before anything is recorded.

    Evidence

    3 / 4

    Relevant source use; one explanation needs teacher review.

    Organization

    4 / 4

    Clear claim and logical paragraph sequence.

    Style

    2 / 4

    Sentence variety is developing.

  4. CAPABILITY 04

    Review controls stay explicit

    Every AI suggestion is optional. Teachers can read the reasoning, edit feedback, override scores, and leave work pending until they are ready to approve.

    • Teacher review required
    • Editable feedback drafts
    • Score overrides remain explicit

    Product preview

    Teacher review

    Editable draft

    Essay context

    Claim, evidence, and explanation appear beside the rubric so the teacher can verify the draft.

    Use of Evidence

    AI confidence: medium

    AI draft score: 3 / 4

    Evidence is relevant and mostly explained. One source needs a clearer link back to the claim before approval.

  5. CAPABILITY 05

    Grade locking and exports are separate

    Approved grades stay pending until the teacher locks them. Export reports and CSV summaries are available when reviewed feedback is ready to share or archive.

    • Grades lock only after approval
    • PDF and CSV exports
    • Audit-friendly review trail

  6. CAPABILITY 06

    Class patterns inform the next lesson

    Rubric results can become class-level patterns, common skill gaps, and a teacher worklist so grading evidence points toward what to reteach next.

    • Class heatmap by rubric skill
    • Common issues and score distributions
    • Prioritized teacher worklist

School and district

Implementation Controls

School and district controls are available after approved setup. Manual upload remains available for individual teachers. Connected classroom, LMS, roster, and SSO workflows require school or district approval.

Users and licenses

Manage staff invitations, school roles, permissions, and purchased seat assignments from district administration.

Usage insights

View aggregate adoption, grading activity, and writing trends without exposing individual student essays or grades.

Compliance workflows

Track retention settings, export requests, deletion requests, and implementation handoffs in one place.

Content library

Publish approved rubrics and writing resources for teachers to reuse within an implementation.

Launch readiness

Coordinate rollout tasks, owners, due dates, and launch summaries for school or district teams.

Approved integrations

Manual upload is always available. Google Classroom workflows are available only where connected and approved. Canvas, Schoology, Clever, ClassLink, OneRoster, and district SSO require school or district approval, setup, and applicable provider terms.

Integration support does not imply provider certification, marketplace listing, or automatic production enablement for every customer.

Trust and privacy

Built with teacher trust at the core.

Student work is handled as education data. The public promise is intentionally narrow: the AI prepares drafts, the teacher decides, and data-use claims stay tied to the product behavior we ship.

Designed for FERPA-aware classrooms

Grade Harbor is teacher-facing, does not require student accounts, and uses student data only to provide grading and feedback services. We do not use Student Data to train generalized AI models without explicit written authorization from the applicable school, district, or authorized educational institution.

No data selling - ever

Student essays, rubrics, scores, and feedback are never sold, licensed, or used for advertising.
Read our Privacy Policy

Teacher always in control

No grade is recorded, no feedback is shared, and no instructional action is taken without explicit teacher approval.
