Enterprise ArchitectureBuilt on Microsoft Azure

From raw student responses to actionable learning signals.

ClassSignal leverages the Microsoft Azure Cognitive and Cloud stack to analyze response-level student assessment data at scale. The system computes what the evidence indicates — educators decide how to teach.

Cloud & AI Foundation

Powered by Microsoft Azure Cognitive Stack

Enterprise-grade scalability, sub-second inference, and rigorous student data privacy built directly into the core infrastructure.

Reasoning & Pedagogy

Azure OpenAI Service

Powers pedagogical misconception detection, cognitive error clustering, and automated teacher micro-intervention synthesis using fine-tuned reasoning models.

Computer Vision & OCR

Azure AI Document Intelligence

Ingests scanned handwritten student test papers, mathematical notation, and digital exam scripts with sub-character accuracy.

Multi-Model Data Store

Azure Cosmos DB

Stores student response trees, historical cohort mastery records, and national curriculum taxonomy graphs with sub-10ms global latency.

Vector Embeddings

Azure AI Search (Cognitive Search)

Semantic vector indexing that maps student errors directly to national curriculum standards (WAEC, IGCSE, US Common Core, IB).

Compute & Orchestration

Azure Kubernetes Service (AKS)

Elastic container orchestration that scales automatically during peak end-of-term school examination periods.

Analytics & ETL

Azure Data Factory & Synapse

Aggregates multi-school cohort benchmarks, learning poverty metrics, and longitudinal intervention efficacy for NGOs and school networks.

Processing Pipeline

End-to-end telemetry workflow

How student script data traverses our Azure pipeline to generate an 85% review efficiency turnaround for teaching teams.

  1. 01

    Assessment Ingestion

    Azure AI Document Intelligence + Blob Storage

    Student test papers (handwritten or digital) are securely uploaded and transformed into structured response data.

  2. 02

    Semantic Parsing & Vectorization

    Azure AI Search + Text Analytics

    Individual answers and multi-step workings are vectorized and mapped to curriculum learning objectives.

  3. 03

    Cohort Pattern Detection

    Azure OpenAI Diagnostic Pipeline

    Clustering algorithms separate isolated student slips from shared, systemic conceptual misconceptions across the class.

  4. 04

    Intervention Generation

    Fine-Tuned Pedagogical LLMs

    Synthesizes concise 10-minute classroom remediation strategies and whiteboard checks tailored to the specific error pattern.

  5. 05

    Teacher & Network Dispatch

    Azure SignalR + App Service API

    Pushes real-time diagnostic signals to the teacher's cockpit, school leader dashboards, and network LMS systems.

Security & Student Privacy

Enterprise data sovereignty & FERPA/GDPR compliance

ClassSignal enforces strict zero-trust data segregation for every school network, NGO partner, and district tenant.

Student assessment data is anonymized at the ingestion boundary before entering Azure AI processing pipelines. No student PII is used to train public foundational models.
