This study examined Spanish spelling errors among 166 native Spanish-speaking students from Kindergarten to Grade 3 based on a spelling-to-diction task. Fifteen types of spelling errors were analyzed in a latent class analysis. Results suggested three phases of spellers: Phase 1 students had a high chance of committing almost all types of errors. Phase 2 students had a lower chance of committing vowel-based phonological errors, but still had a high chance of committing consonant-based phonological errors. Phase 3 students had some difficulty differentiating distinct but similar consonant sounds for spelling (e.g., spelling "reptile" [reptile] as "rebtil"; "Diente" [tooth] as "viente"). Among the word-context factors, syllable complexity and orthography difficulty were the best predictors of phonological and orthographic errors in more proficient spellers, respectively. We suggest that awareness of Spanish vowel and consonant sounds may not grow in tandem, and future research should incorporate word-context features into spelling error analysis.
