We have the same issue still with our almost 12 year old son. However, as I was reading this post. I realized that I am just as likely to put off the boring repetitive aspects of my job. I'm typing this while a data entry project stares me in the face. However, i did do all my analysis work and reporting that actually takes thought to complete.

Now, I'm thinking I should have more patience with our son. I can't imagine going back to 6-7 hours of boredom every day and getting the assignments completed correctly and on time.

I don't really know a solution. In our state we can request in school testing before grade 3. Is that an option for you? The downside is that it can take about 4 school months to get it completed. Are you seeing emotional side effects? This might be a way to get something done before that 3rd grade cut off.

Good Luck!
