Validity of DIBELS

Some important concerns are:



  • Does DIBELS have evidence of validity especially predicting success and difficulty achieving important reading outcomes?


  • Despite their labels, DIBELS is not a valid test of the constructor of fluency. They assess accuracy and speed.
  • Misuse of the term validity when there’s not enough statistical data

Administrative considerations meant to ensure reliability of DIBELS results: 

  • Criterion-related validity studied in eight separate studies in the 1980s reported coefficients ranging from .52-.91
