The Dynamic Indicators of Basic Early Literacy Skills (DIEBELS®) is an instrument that can be used to measure literacy and reading skills acquisition. It is comprised of multiple, short, fluency measures that allow educators to monitor development and identify risks in these domains. Subtests predict later reading proficiency and later reading development.
- Letter-naming fluency (LNF)
- Phonemic segmentation fluency (PSF)
- Nonsense word fluency (NWF)
- Word reading fluency (WRF)
- First sound fluency (FSF)
- Initial sound fluency (ISF)
- Word use fluency (WUF)
- Retell fluency (RTF)
Total Time: one minute per fluency measure
Reliability: acceptable on test-retest, alternate forms, and inter-rater (Kaminski 1996)
Validity: demonstrated criterion-related validity (Hintze 2003)
