My twins were given the ITBS and they are in first grade
One twin scored 27% Reading 99% Math
Second Twin 93% Reading 95% Math

Second twin is was accepted into the gifted program, they want to retest the other next yr.

I was told this is an IQ test but no one will give me the break down on how these percentages turn into an IQ score. I've tried googling it and just become more confused.

Thank you for any assistance
