“…There are several spelling error analytic approaches that are informed by a multilinguistic understanding of spelling, including Multiple Linguistic Coding (MLC; Apel & Masterson, 2001;Bowers et al, 2014), Spelling Sensitivity Score (SSS; Masterson & Apel, 2010b), The Phonological, Orthographic, and Morphological Assessment of Spelling (Bahr et al, 2012;Silliman et al, 2006), POMplexity (Bahr et al, 2020;Benson-Goldberg, 2014), and POMplexity for Roots and Affixes (Quick & Erickson, 2018;Quick et al, 2019). All of these tools infer children's linguistic knowledge or strategies from their spelling errors (Devonshire & Fluck, 2010), but they vary in their approach.…”
