UDS: OMR Answer Sheet Scoring – Web Portal & API

UDS OMR Answer Sheet Scoring is a professional service for automated grading of exam answer sheets using a proprietary Optical Mark Recognition (OMR) algorithm. The solution is designed for educational institutions, testing providers, and organizations that require fast, accurate, and scalable exam processing. The service is available in two formats: Web Portal and API. Through the Web Portal, users can upload PDF or image files of answer sheets and receive detailed performance reports, statistics, and question-level analytics. Using the API, customers can integrate the service directly into their systems, sending exam data and receiving structured JSON responses that include student names, scores, and additional metadata. The architecture leverages AWS services to ensure scalability and reliability. The core application runs on Amazon ECS, while an AWS Lambda function executes the proprietary OMR algorithm. Amazon Textract extracts contextual information such as student name and registration number, and Amazon Bedrock organizes and refines this data to deliver consistent and structured reports. The unique value of the solution lies in its proprietary OMR algorithm, capable of accurately detecting responses across multiple answer sheet layouts. This minimizes errors common in manual or generic solutions and delivers greater reliability, operational efficiency, and reduced costs. With UDS OMR Answer Sheet Scoring, organizations gain a complete and secure solution available on AWS Marketplace that automates exam grading and provides actionable insights through advanced reporting and analytics.
