| DIBELS~Dynamic Indicators of Basic Early Literacy Skills |
| DIBELS are brief measures of the critical skills that underlie early reading success and are grade specific. Benchmark assessments are given to all children in a grade. OPS is currently using DIBELS assessments with all students in Grades K-4. Listed below is a description of each DIBELS measure. |
Initial Sound Fluency (Beginning and Middle of Kindergarten) ISF measures the child's ability to identify, isolate, and pronounce the first sound of an orally presented word. The score is the number of correct initial sounds given per minute. |
Letter Naming Fluency (Beginning Kindergarten through Beginning of Grade 1) LNF measures the child's ability to name as many letters as possible, uppercase and lowercase randomly mixed, within one minute. |
Phonemic Segmentation Fluency (Middle of Kindergarten through Grade 1) PSF measures the ability to take apart and pronounce the sounds of a word or syllable with three or four phonemes. For example, the word sat should be pronounced using the phonemes /s/ /a/ /t/. The score is the number of correct phonemes produced in one minute. |
Nonsense Word Fluency (Middle of Kindergarten through Beginning of Grade 2) NWF measures the ability to link letters with sounds and use that knowledge to decode three-letter syllables that alone are nonsense words (sis, sil, com). The child receives credit for pronouncing individual sounds or the correct sounds in a whole syllable read as a unit. The score is the number of letter-sounds correct in one minute. |
Oral Reading Fluency (Middle of Grade 1 through Grade 4) Benchmark passages at each grade level are used to measure accuracy and speed in oral reading of graded passages. This measure is used to identify children in need of additional assessment and intervention and to monitor reading progress. Students read each of three passages aloud for one minute. The student's score is the median correct words per minute from the three passages. |
