Overview
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:
