Teach Your Child to Read in 100 Easy Lessons is *not* a complete phonics program - it provides a good jumpstart to sound blending and some basic phonics but that's it. DS and I really enjoyed it but I also had to draw a lot on my own knowledge and memory of phonetic rules and rhymes, and once we finished doing it (stopped around lesson 75 IIRC) then I used some other phonics tools to help him with things he still wasn't solid on (like some vowel blends and knowing when to pronounce with a long vs. short vowel sound).
I thought Hooked on Phonics was supposed to be pretty complete though
. I have HS friends whose kids learned to read from it.
I would expect if you did every single workbook in Explode the Code it would be considered complete - not sure as we just did part of the first workbook and I found it rather dull and boring. It didn't help DS on his path to reading although he liked circling the letters and scribbling in it.
I think Sing, Spell, Read and Write is probably a 'complete' program - it is very thorough (based on my memory of how it worked).
I would suspect that if you did the entire Ordinary Parents Guide to Teaching Reading it would also be considered complete, though I found it terribly dull and only used it as a reference for what phonics rules DS did and didn't know yet so I could explain the new ones in books as we read - I didn't use the book's method with him.
Those are the main programs I can think of...he also plays on Starfall and I got the Leap Frog "Letter Factory" DVD's from the library for him to watch - the songs about the different vowel patterns were helpful for him.
That's my entire experience and knowledge of different reading programs - it's still pretty fresh in my mind b/c DS just learned to read this year.
