On-Screen Marking for Engineering & Polytechnic Exams
Engineering and polytechnic exams have unique evaluation challenges — diagrams, circuit drawings, mathematical derivations, and multi-part problems. MAPLES OSM is built to handle all of them with high-resolution scanning and purpose-built marking tools.
Why Engineering Exams Need Specialized Tools
Unlike text-heavy humanities exams, engineering answer scripts contain a mix of content types that standard evaluation tools struggle with:
- Diagrams, circuit drawings, and flowcharts that need fine-detail scanning
- Mathematical derivations spanning multiple pages with intermediate steps
- Multi-part problems (Q1a, Q1b, Q1c) requiring separate marks for each sub-question
- Mixed content — text, equations, graphs, and hand-drawn figures on the same page
- Lab drawings and design sketches requiring evaluator markup and annotation
How MAPLES OSM Handles It
High-Resolution Scanning
Overhead camera stations capture fine details — circuit diagrams, mathematical symbols, and hand-drawn figures are clearly readable on screen.
50-150% Zoom
Evaluators can zoom from 50% (full-page overview) to 150% (fine detail) — critical for reading small handwriting, circuit components, and graph labels.
Freehand Annotation Tools
Mark directly on diagrams, circle errors in circuits, annotate derivation steps. Freehand drawing, text boxes, stamps, and highlighting included.
Hierarchical Question Structure
Support for Q1a, Q1b, Q1c with separate mark fields for each sub-question. Automatic totaling with configurable maximum marks per part.
Sub-question Validation
System validates that marks for each sub-question do not exceed the maximum. Total marks are auto-calculated and checked against question paper totals.
Double Valuation for Technical Subjects
Engineering answers are subjective — double valuation with automatic discrepancy detection ensures fair marking for derivations and design problems.
Side-by-side Marking View
View the answer script on one side and the marking scheme on the other. Evaluators can reference model answers while marking.
Subject-wise Analytics
Track pass percentages, average marks, and evaluator marking patterns per subject. Identify statistical outliers before results are finalized.
Proven at Scale: DOTE Tamil Nadu
MAPLES OSM powers on-screen marking for the Directorate of Technical Education (DOTE), Tamil Nadu — covering polytechnic engineering exams across the entire state.
Engineering Evaluation Workflow
- Inwarding — barcode/QR tracking for every booklet received at the scanning centre
- Scanning — high-resolution capture with automatic page ordering and quality validation
- Randomization — student identity stripped, scripts shuffled across evaluator pool
- On-screen marking — question-by-question evaluation with sub-question support and annotation tools
- Double valuation — automatic discrepancy detection with third evaluator assignment
- Moderation — subject-wise moderator review with statistical analysis
- Result validation — 9-point automated checks before finalization
- Result publication — grade cards and mark sheets via student portal
