Thank you. I, too, agree that my children likely would be quite bored in 1st grade. I feel very fortunate that we home school, so I can side-step some of the boredom issues.

To help future parents trying to compile a portfolio, I'd like to share the e-mail response I received from a Davidson consultant regarding my questions about the portfolio contents. First, they are fine with a video of a child explaining an out-of-level concept, like nuclear fusion and photons traveling through the sun's layers, even though the child obviously is communicating information they have been taught, not original ideas. Second, chess is considered a non-academic example, so parents may want to be mindful that a video of chess doesn't count as one of the four portfolio items.

Thank you so much to all the people who have taken the time to assist me. I hope this thread helps future applicants, too!
