I am also in MD. Last year (kids were 4th and 7th) we went in with portfolios, the kids workbooks and other work of choice, and a large photo album we put together. I dreaded it for weeks, to the point of loosing sleep! It was not that bad at all. The homeschool principal spoke briefly with me, then with each of my children all while looking at the portfolios. Then he took time to look at the photos with my kids and listened to what they wished to tell him. It was really neat actually. He stressed to my kids that they were lucky to have parents willing to homeschool, that they need to work hard and do their best, and that he could tell they worked really hard this year. It turned out to be such a positive experience and I can see a difference in my son this year already. He has even asked when we would get to see him again, lol. It helped her feel she was truly ready!
Which county are you in? We are in Charles.
