This chart shows the progress our students have made to reach their school grade reading level. Grade-level reading is based on three assessment measures: *DIBELS®, Slossen grade-level word lists, and assessment of ability to decode multi-syllable nonsense words that follow English spelling rules. *DIBELS® is the Dynamic Indicators of Basic Early Literacy (a proven, standardized, and normed assessment). It is used to predict the likelihood of achieving subsequent literacy goals.
