khbmom,
The ladies have already done a great job of helping you! I'll just pop-in to mention what I've found to be true from my public school teaching days where we pretested kiddos every week. We discovered that pre-testing is a less than accurate read on whether our kiddos actually "know" the word or not. Sometimes they may really know it, and other times they may just have guessed and gotten it right or have "known" it in the short-term only to have "lost" it in the long-term.

So with any of our guides, we actually don't recommend pre-testing. We feel the words in List 1 and List 2 are so important to know that we like all kiddos to go through them, whether they seem to know the words on the list right on the first day or not.
At our house, we don't pretest the kiddos but rather have a first grader do List 1 and a second grader do List 2, no matter whether that child is a terrific speller or not. This is because these words are so important to know that it's good practice to go over them and to practice the activities that are designed to help a kiddo visualize the word in his/her mind at the same time. Both of my oldest two sons were terrific natural spellers. They went through the lists anyway, and it didn't hold them back in their spelling abilities or spelling scores in end-of-the-year testing at all. It taught them to visualize words and to "see" them in their minds before spelling them.

My oldest son only missed one word all year! Yet, for me it was worth it to be sure the techniques were practiced prior to the visualizing needed for studied dictation.
My third little guy is not a natural speller. His hearing issues have made it hard for him to hear the sounds. He did all of List 1 as a first grader and will do all of List 2 as a second grader too, moving steadily forward each week.

Anyway, you get the idea. So, in your situation I would recommend doing the spelling plans as written, with no pre-testing, as the visualizing technique is as important as knowing the words themselves.
Blessings,
Carrie
