If you don’t plan on continuing with homeschooling, do not use Sonlight!
I just spent the entire year teaching Sonlight K curriculum to my kindergarten age daughter. I am considering moving her to a Christian Classical school for first grade.
Today, she was tested and I was told she may have to repeat kindergarten if we don’t spend the summer getting her caught up. Granted, this school is advanced–they use Saxon Math 2 in 1st grade, but because of (the literature base) all of the time I spent reading to her, she wasn’t able to complete the phonics testing.
I am now regretting choosing Sonlight. I wish I would have skipped all of the fantasy stories and spent more time having her read to me and more effort on Phonics and Math. I suppose if you are going to continue homeschooling (for sure), this may work for you, but in my case, it failed miserably.
