Qualitative descriptors for BDI-3

🔧 Steps

1. Refer to page 101 of the BDI-3® Examiner’s Manual for a full list of descriptors.

2. Alternatively, log into Riverside Score®.

3. Navigate to the Resources tab.

4. Locate the DQ Proficiency Range Chart under Technical Manuals.

📝 Additional Notes

• These descriptors provide context for a child’s developmental progress and help support recommendations for intervention services.

• The chart includes ranges for labels such as Average, Below Average, and Above Average, in addition to developmental delays.
