integration back into school

My daughter is in the first grade at public school and really enjoys it. We want more for her, though, and will begin using the Latin-based Curriculum as the basis for homeschooling beginning in January (we will be taking her out of school). In all my excitement, fear, anticipation, dreaming, fear for the prospect of homeschooling I'm trying to make the best decision for my children. In that decision I want to know that if something happens in the course of our lives (homeschooling doesn't seem to work for us, or I die) where does that leave my children regarding their education? Using this curriculum will they be able to integrate back into school at the appropriate grade?
