    From going through it with my older child, I see Algebra II as a natural extension of Algebra I (i.e., higher order equations and more emphasis on systems of equations). That's why I would not consider advocating skipping Algebra I. It is important to my thinking that the Algebra foundation be super strong and automatic.

    As an example of why I don't think he should skip Algebra I notwithstanding chapter pretest scores of mid-80's to mid-90's: I have seen him solve an equation in five steps instead of 4. While I always emphasize that there is a number of ways to solve a problem and it is good to see multiple ways, it is equally important as he progresses to higher mathematics to be able to immediately see the most elegant and efficient approach.

    LOL about the birds! That's reminds me that proper use of the correct vocabulary/terminology is another reason that I would not consider skipping Algebra I .

    I suppose that Pre-algebra can be whatever the school elects to include. Unlike Val's description of California math curriculum, about 40% of DS' Pre-algebra curriculum would be more properly label Pre-geometry & Pre-trigonometry. In fact, I think the course may finally be relabeled. Probably something like [SPAM] to algebra and geometry.

    Interestingly, I took Pre-algebra over three decades ago and while we covered geometry topics there were no coverage of basic trigonometry. Come to think of it, I am not sure if the non-GT Pre-algebra covers exactly the same topics.

    Polarbear, I think you are exactly on point. Interestingly, in my day (well over 3 decades ago), the Pre-algebra course was to get the advanced kids out of 7th grade math and onto more advanced concepts.

    LOL. DS scored a 96% on the last chapter pretest. It would be really sad if he scores lower on the end of chapter test.

    Thanks for reminding me of that book. I have a copy and read it a couple of years ago but didn't remember about the 85% guideline discussed in the book. I do wonder though if the model should apply equally as you move higher in math since that book seem more geared toward elementary and middle school.

    The idea is that he fills the 'gaps' as he encounters them. Too much repetition => boredom and decrease in motivation. (Much discussed in this forum.)

    Example (an actual Alcumus AOPS problem): "Represent 39/2500 as a decimal.". DC does long division, then sees a shorter solution (multiplying both parts by 4) - he'll know in the future to look at the particulars of the numbers first.

    (I'm actually not trying to sway you one way or the other, because your final decision may be driven by very practical considerations - e. g., whether he'll have to work completely on his own, without outside help.)

    I am glad to read an opinion different from my own. That's why this forum is so useful. It actually isn't a question of DS skipping Algebra I, but rather an issue of how comfortable I am in allowing him to zoom through the Algebra I course. If he does zoom through it, then there is the question of what to do with him the rest of the year.

    Quantum2003, I misread your original post. Sorry! I thought your DS was in pre-algebra now.

    No problem. Your input was still relevant.
