I think it's a good sign. I agree with mnmom - you don't have to agree to anything yet. But I would take notes if I were you, and send a follow-up email afterwards listing the things you believe were discussed.
I would imagine that a curriculum director might be concerned with the dreaded "GAPS", so be prepared for some talk like that. Most elem. curriculum is very circular, repeating many concepts several times. Many HG kids don't need this, and if they miss a year early on, it's likely that they still already know the subject matter or else they can get it if explained quickly to them. We have heard things after a test like "your DS did not know THIS, which is very surprising considering how smart you think he is". (Well, not exactly that, but it felt like that!) My response was that he still needs to be taught things - he can't learn everything through osmosis (though sometimes it seems he does). But he can learn concepts much more quickly than the average bear.
If they want to do testing, first see if any testing you may already have will be sufficient. (Although many HG kids like all this testing, it is stressful for some.)
If they offer a skip sooner, I would think hard. It sounds like you have a great setup with the every other day kindy - something that would have been perfect for our DS. If it were me, I would ask if there's anything that can be done in terms of curriculum compacting and/or differentiation while he's still in every other day kindy.
First grade is typically a learn to read/learn to do very basic math year, all of which your DS probably already knows. So first grade can be a very tough year for HG kids. If they start leaning toward 1st plus differentiation, I would ask for the skip, as it's likely that even in 2nd grade your kiddo will need differentiation, and it's a lot easier to differentiate if the baseline instruction is closer to the needed level. Also more likely that there will be other kids in 2nd grade that will be close to your DS's level in certain subjects.
Do you or the school have a copy of the Iowa Acceleration Scales? Very objective way to determine if a student is appropriate for full grade skip. (I have a feeling your DS would score highly). Ask the school about this.
I may have asked this before, but how is your DS with handwriting? If this comes up as a concern, you can offer to work with him at home on this, and ask if you can get a handwriting program the school uses so your son will be learning the same stuff that the other kids learned. Handwriting without Tears is also a great program.
Do you have a DH or other partner? Take that person with you so you present a united front and also so you can remember everything.
Good luck!
