Typically, spelling instruction should be fully interconnected with reading instruction. Therefore, during reading tutoring, spelling will be fully addressed.
When a student is struggling SOLELY in spelling, and is an excellent reader, it is important to determine the foundational reason for this type of spelling difficulty. Quite often, there is an actual root in phonological processing which must be addressed. An assessment can determine whether or not this is a deficit skill which needs addressing.
Links regarding spelling:
Students who struggle with paragraph writing often have what is called "dysgraphia." One of the best (if not THE best!) programs for writing skills is called Institute for Excellence in Writing. This program is designed with parent workshop DVD's to teach the parent or classroom teacher how to teach the program.
If your child is receiving tutoring in the Barton Reading and Spelling System, s/he will also be tutored in sentence-writing skills beginning in Level 3. When s/he is ready for more formal paragraph-writing instruction, IEW is the next step.
The parents might want to do this tutoring themselves. If not, you can request to be referred to a certified instructor in IEW who might have openings for tutoring.
