#### **Introducing the WJ V RAPID NUMBER NAMING Test**

Processing speed and retrieval fluency are essential for academic success. These skills influence how efficiently students can access and verbalize information, impacting performance in reading, math, and across subject areas. By identifying strengths and challenges in these domains, educators can better support learning and intervention strategies.

The Rapid Number Naming Test is a quick, oral measure designed to evaluate how efficiently examinees can identify and name numbers in sequence. Recommended for ages 4 and up, this one-minute assessment provides valuable insight into two CHC broad abilities: processing speed (Gs) and retrieval fluency (Gr). It contributes to the Rapid Automatized Naming (RAN)–Math cluster, offering a targeted look at skills that are foundational for academic performance.

**Why Choose the WJ V Rapid Number Naming Test?**

1. **Quick & Efficient**
   
   A 1-minute timed format captures immediate insight into processing speed and fluency without disrupting instruction.
2. CHC-Aligned
   
   Directly measures two key broad abilities—processing speed (Gs) and retrieval fluency (Gr).
3. Reliable & Valid
   
   Demonstrates strong reliability, with alternate-form coefficients as high as .97 for ages 4–19 and .89 for ages 20–80+.
4. Equipped for Equity
   
   A backup form is available to ensure validity if administration is interrupted, maintaining fairness and consistency.

**How It Works**

Examinees are shown rows of numbers on a tablet and asked to name them aloud as quickly and accurately as possible. After a brief sample to confirm understanding, the timed test begins. Scoring is automated, with results reported as decile scores (0–9) that give examiners clear, actionable insights into a student’s processing fluency.

Unlock Fluency Insights with Confidence

The WJ V Rapid Number Naming Test offers a precise, time-efficient way to evaluate processing speed and retrieval fluency. Use it to identify learning needs, guide interventions, and strengthen academic evaluations.
