How GradingPal's AI Science Grader Works
End-to-end encrypted, FERPA-compliant, and never uses student data for model training.
Create Assignment
Choose "Worksheets," "Problem Sets," "Exams," or "Labs" and upload your blank master PDF or image.
Apply Rubric
Select a pre-built NGSS template or build your own with the intuitive drag-and-drop rubric builder.
Upload Student Work
Batch upload scanned PDFs or digital files. Advanced OCR automatically extracts handwritten responses, diagrams, data tables, and conclusions with 95%+ accuracy.
AI Scoring & Feedback
The AI applies your rubric and generates targeted feedback (e.g., "Strong data collection — add error analysis and connect to energy transfer for Level 4").
Review & Analyze
Use the real-time analytics dashboard to identify class-wide trends and individual progress.
Export & Sync
One-click export of scores and feedback directly to Google Classroom.
Key Benefits for K-12 Science Teachers
Massive Time Savings
Teachers typically reclaim 60-80% of science lab grading time — an average of 5.9 hours per week.
Precise, NGSS-Aligned Feedback
Students receive specific comments on scientific practices, data analysis, experimental design, and conclusions.
Standards-Based Grading Made Simple
Pre-built and custom rubrics aligned with NGSS performance expectations (e.g., HS-PS1-2, MS-LS1-2, HS-PS3-1).
Equity & Fairness
Consistent rubric application reduces bias; OCR ensures handwritten diagrams and lab notes are graded fairly.
Powerful Insights
Real-time analytics help you identify learning gaps (e.g., "65% of class struggled with data interpretation") and plan targeted reteaching.
Seamless Integration
Direct sync with Google Classroom eliminates manual grade entry.
Real-World Use Cases in Science
