About Forecasting REST API

The Forecasting API forecasts an individual student or group performance on an upcoming assessment. To accomplish this, the API uses a proprietary growth model, prior information about a student or group of students, and information about an examination to be taken in the future.

When making a call to the API you will need to include testUncertainty and cutLevels of tests that student performance is being forecasted to. MetaMetrics sends this information in spreadsheet format via email. If you have not received the spreadsheet please reach out to your MetaMetrics representative or the person in your company who is the MetaMetrics point of contact.

The Forecasting API uses a standard REST interface. This documentation provides information and example code to assist you in integrating the REST API into your application.
