In the NSPA Scholarship Program Data Standard, requirements based on GPA are coded in the Academic Eligibility entity. By definition, U.S. values are encoded on an unweighted 4.0 scale, including a decimal value.

This document provides recommended conversions both to and from the 4.0 Scale:

1 Conversions to 4.0 Scale (U.S.)
2 Conversions From 4.0 Scale (U.S.)
