Test Scoring
IDP offers a free test scoring and analysis service for objective, multiple-choice examinations on the West Lafayette campus. The service provides high levels of reliability, accuracy, and security with a 24 to 48-hour turnaround time.
All information and materials needed for the service, including the free machine-readable student response forms, can be obtained from IDP in Room G-61, Stewart Center. Response forms should also be returned to G-61 for scoring and analysis.
For customers who use both Scantrons and Gradescope, IDP will either scan exams for Gradescope or process Scantrons for an exam. To ensure accuracy and efficiency, we cannot provide both services for the same exam.
