What are Dynamic Indicators of Basic Early Literacy Skills (DIBELS)?
• The DIBELS measures were specifically designed to assess 3 of the 5 Big Ideas of early literacy: Phonological Awareness, Alphabetic Principle, and Fluency with Connected Text (click here to link to Big Ideas in Beginning Reading for more information on each of these domains). The measures are linked to one another, both psychometrically and theoretically, and have been found to be predictive of later reading proficiency. • Measures of Phonological Awareness: • Initial Sounds Fluency (ISF): Assesses a child’s skill to identify and produce the initial sound of a given word (click here for a longer description and to learn how to administer and score the ISF measure). • Phonemic Segmentation Fluency (PSF): Assesses a child’s skill to produce the individual sounds within a given word (click here for a longer description and to learn how to administer and score the PSF measure). • Measure of Alphabetic Principle: • Nonsense Word Fluency (NWF): Assesses a child’s knowledge of letter-sound
