What is RAN?

Rapid Automatized Naming (RAN) is a task that involves quickly and accurately naming repeated sets of familiar items. RAN measures are brief, individually administered assessments that are used in kindergarten and first grade. 

Why Use Acadience RAN?

Acadience RAN is an optional measure that can be used along with Acadience Reading K–6. RAN is a helpful tool for educators because it:

  • is a brief assessment that can be used to screen students for reading difficulties such as dyslexia
  • is typically a good predictor of future reading difficulties
  • is based on decades of research by multiple researchers
  • includes a RAN Objects, Letters, and Numbers task
  • is available in Spanish
