Ok - take a deep breath. Even if school starts tommorow, you are not too late. Make an appointment with the Gifted Specialist. By my personal guess, you have about a month before the newness of school wears off and the fireworks begin. OTOH, I've heard of kids who "quit" after the first day. Be prepared to believe him. Afterall, how would your second grader feel if they arrived at the first day of school and sent to the kindergarden classroom.
Also, don't let the "we don't have a program" line throw you. Of course they don't have a program for a kid who is reading at 2. There are no "programs" for kids like this, only schools were they access the needs of individal students and make a plan to meet them. Karen Roger's book re-forming gifted education is terrific here. Iowa Acceleration Scale Manual also terrific - just order both from Amazon, now, and get it over with. If you are in a spending mood, get Ruf's Losing our Minds as well, It has a whole cheat sheet in the back of "if my kid is doing this" and "my school is like this" what can be expected.
Here are some questions to ask yourself.
1) How do I feel about grade skipping?
2) How do I feel about homeschooling?
3) Am I ready to have ds tested?
4) Is it a half day kindergarden?
5) Are there any gifted school in my area? Montesori with multiage classrooms?
6) Does he tolerate agemates well? Has he been in daycare or preschool?
7) What is going on that I waited so long to think about this? Am I in "gifted denial"
Some kids have done well for a whole year in K if it's not very academic and a half day to play with others. (Then they skip first, and go directly into second, and keep skipping as needed.) My son, at age 8, said, "They make kindergarden fun in order to brain wash you that school is good, and get you in the habit of going." More recently, at age 10, he was able to look back and say - "My goodness! I was SO bored in kindergarden, and I didn't even realize it because I was so young." Listening to kids reflect on their own lives is always chancy, but I think you see the general theme - when they are this young, they have a difficult time expressing how they feel in an "overall" sense.

Download the application
