There is a big thick line between bright and gifted however many parents make the mistake of thinking their child is gifted when indeed they are bright. I read an article a while ago that gave some tips on making the distinction. Is your child bored in class? Does your child work really hard to get good test grades or do they not study at all and still achieve high grades? The article also stated that "genius" children tend to debate their teachers and can be seen as having behavioral issues when in fact they are just challenging their teachers knowledge subconsciously.

My husband had many issues in school when he was growing up until his mother took him to a doctor and was given a IQ test in which he scored 132 at the age of 15. He still had to take summer school for English and barely graduated High School even though he passed all his exams with above 90 averages. He also had issues with his fine motor skills, it would take him hours to write out a paper (At the time computers were not very common). Some teachers would get upset when he would correct their mistakes and so they classified him as having attitude problems. He would also space out in class or sleep. My 5 year old daughter was experiencing the same difficulties as my husband when she started school, to the point her teachers said they may have to put her in a special class. They finally tested her and she scored higher than any other Pre-K student by a huge margin. This is where discussion of skipping grades began for me. I personally don't want to skip her until she has taken more tests and I can see taking that step will truly benefit her.

Healthy11 is 100% right a IQ of 150 is incredibly high and is above the "requirement" of being classified as a genius, 110-115 is quite average. Make sure you don't put your daughter in a situation where she is frustrated because she can't keep up with the other children. Other than that you're lucky to have a child that is performing so well, good luck.
