WeaverÆ Success in spelling Level 4 is for students in grade 5 who've completed the previous levels, but it may be used as a stand-alone program, too. The 66 lessons detail homophones, accented syllables, special spelling rules, and short and long vowel spellings. Diacritical markings and syllabication are also included.

In the curriculum, two kinds of word lists are included: a master list for the teacher which includes diacritical markings and syllabication for each word, and pretest lesson forms for the student. Weekly instructions contain daily assignments, such as writing words, defining words, and breaking words into syllables, as well as fun activities for memory reinforcement. Level 4 begins with words like raised and razed; pore and pour; and blue and blew; and ends with words like dogmatically, skeptical, seizure, and persuasion.
