Reporting Forecasting Measures
The Forecasting API uses the Lexile® and Quantile® frameworks to calculate student
measures (called ability
in the API response).
For detailed information about each framework and measures see:
The calls in the Forecasting API return a measure and uncertainty. If the measures are being used for research or institutional purposes, they can be used as reported.
If the measures are used for reporting to teachers, parents, and students then proper branding needs to be applied. To do this:
-
Round the measure to the nearest 5th integer. For example if:
- A measure is 572 it should be rounded to 570.
- A measure is 577 it should be rounded to 575.
- Add L (for Lexile) or Q (for Quantile) to the end of the measure. For example: 575Q.
-
If a measure starts with - (negative sign) replace the negative sign
with:
- BR (for Lexile). BR stands for Beginning Reader.
- EM (for Quantile). EM stands for Emerging Mathematician.
- For example BR100L.
