My understanding is that Character Quality Language Arts (CQLA) is a comprehensive LA program ("English" which includes spelling, grammar, composition) but Meaningful Composition (written by the same author) is ONLY the composition aspect of their LA curriculum because some moms were happy with a separate spelling, grammar, etc. program. Just ordered MC so can't give specifics yet.
I have IEW and really like it but seems like MC, based on IEW, directs the student's writing step-by-step using a consumable workbook. The extra hand-holding will be exactly what my dd needs. I like the Composition Checklist that MC utilizes which aids the student in editing their own work to determine if they've capitalized their sentences, used proper punctuation, included strong verbs and quality adjectives, etc... I intend to use a combination of both IEW & MC.
