Final answer:
The DIBELS assessment that measures a student's phonic skills is the DIBELS Phoneme Segmentation Fluency (PSF) assessment.
Step-by-step explanation:
The DIBELS assessment that measures a student's phonics skills is the DIBELS Phoneme Segmentation Fluency (PSF) assessment.
The PSF assessment measures a student's ability to segment words into individual sounds or phonemes. Students are asked to say the sounds they hear in a word, such as /c/-/a/-/t/ for the word 'cat'.
By assessing a student's phoneme segmentation fluency, the PSF assessment helps identify areas where students may need additional support in developing their phonics skills.
