How ClassGrade creates value
From curriculum to personalised learning.
Six steps. One platform. Any curriculum, any language, any age group.
Curriculum Embedding
A publisher or school group's curriculum is mapped into a unified learning outcome space. Every topic, concept, and prerequisite relationship is structured. Curriculum-agnostic — UK, Kenya, India, Japan, Italy — all map into the same space.
The multi-curriculum learning outcomes database is the core IP and the moat.
Assessment & Input
Dynamic forms, the exam builder, worksheets, voice tasks. Configurable per school, per publisher, per curriculum. The input layer is flexible enough to handle any assessment format.
Low friction onboarding. Works with existing assessment workflows.
Analysis & Grading
OCR for handwritten work with under 0.5% failure rate. Voice recognition for speaking tasks at 96.7% accuracy. AI-powered rubric scoring. Student work is graded instantly and mapped to learning outcomes.
Proven at scale — 300,000+ students, daily throughput.
Learning Path Mapping
Each student's results position them in the learning space. The system identifies mastery, developing areas, and gaps. Prerequisites are tracked. The knowledge graph shows exactly where each student is and what they need next.
This is what makes ClassGrade adaptive, not just automated. Personalisation at the individual level.
Adaptive Activities & AI Tutor
150+ activity templates, 20,000+ exercises generated from the curriculum. Plus an AI tutor — voice and chat — that adapts tone, difficulty, and focus based on each student's real-time knowledge state.
Two delivery modalities: structured activities and AI tutor. The tutor is the next growth layer.
Reporting & Analytics
School dashboards, teacher reports, parent analytics, publisher-level insights. Real-time, automated, zero admin overhead.
Reporting is how schools justify renewal. It is the retention mechanism.
Architecture
One brand. Three layers.
ClassGrade is a complete platform — not just a website.
Next.js · Web

The school and teacher-facing portal. Dashboards, reports, exam builder, and content library.
React Native · Mobile
App
The student-facing mobile app. Activities, AI tutor, voice assessments, and progress tracking.
Python · Node.js
API
The grading engine, learning path computation, and data layer. Powers both platform and app.
Market Traction
Proven with 300,000+ students across 90+ schools.
ClassGrade is live today — not a pilot, not a prototype. Deployed daily across a national school network with full grading throughput, teacher reporting, and student activity generation.
Publisher pilots are in progress across multiple markets and languages.

Full platform deployment across a franchise network. Daily teacher usage, automated grading, and reporting at scale.
The Opportunity
Static curriculum is becoming adaptive. The transition is underway.
ClassGrade is curriculum-agnostic. It works across languages, frameworks, and age groups. Every publisher that licenses the platform adds a new curriculum to the space — which improves personalisation for every other publisher.
More publishers → more curricula → more students → better personalisation → more publishers.
