This document discusses the Sitton Spelling program which focuses on teaching students to spell words they will use frequently in their writing. It introduces core words divided by grade level based on frequency of use. Students are tested on these words using cloze stories and dictation to identify words they need to study. It also identifies priority words for each grade that students must spell correctly in all their writing. The program builds various spelling, language, and proofreading skills through assessment and word experiences.
