(PSF) Phoneme Segmentation Fluency
Word Reading Fluency
Additional NWF info on scoring words that student recode correctly: "An additional improvement to NWF is that we have reverted to scoring words recoded correctly (WRC; DIBELS 6th Edition practice) rather than whole words read (WWR; DIBELS Next practice). Whereas with WWR students only received credit if they correctly read a nonsense word at first sight (i.e., without sounding out), with WRC they also receive credit if they blend a nonsense word after sounding out the component sounds. Because both methods of scoring predict student risk, in DIBELS 8th Edition, students receive credit for blending nonsense words whether they sound them out first or not. In addition, with WWR the information about students’ ability to blend words was lost if students first verbalized the sounds prior to blending them into words. In this case students would receive no credit for whole words read even though they blended sounds into words. Since the main purpose of NWF is to assess readers’ understanding of the alphabetic principle and sound-symbol correspondence, WRC was deemed the more appropriate scoring method."
