my ds6 (first grade) scored 223 in math for fall this year. One thing we did was look at the breakdown of that score. He scored extremely high in number sense and computation (250's) and relatively lower in geometry and measurement (low 200's). What we decided to do was to focus on his shortcomings and bring this numbers higher. (His spring score was "only" a 206).

Our school is also against acceleration of any kind. They really believe they will be able to continue to differentiate for him.
