Best Practices for Custom Scales
- Non-overlapping Ranges: Keep percentage brackets contiguous without overlaps (for instance, 90–100%, 80–89%, 70–79%).
- Ordered Progression: Ensure higher grades map to higher GPA values and higher percentage spans.
- Full Coverage: Cover from 0% to 100% so any possible test score can be successfully evaluated.
