My son will be taking a gifted test next year. He is currently 3 and attends a 3 year old preschool program. His teacher informed me of the gifted program so my husband and I started early and went to meetings on the program and test.
The most important thing is not to tell your child she is taking a test. The day of the test you just simply tell her she is going to go and play in a room for a little bit. The less they know the better. You do not want to create any anxiety for your child.
If she doesn't get accepted , who cares. It is simply a program that is becoming used more to help those gifted children from getting frustrated in school, and hence getting into trouble or dropping out.
I would read over the characteristics they give you to identify a gifted child and decide for yourself if she matches them. There is a difference between a gifted child and a bright child decide for yourself what you feel your daughter is and then go from there. But make sure not to discuss it to your daughter. The less she knows before the test the better.
I just noticed you live in Brooklyn, My husband grew up in Manhattan and took the gifted test at 4 in Manhattan. I think the gifted programs in the city are a lot different now but I thought I would share this with you. My husband took it when he was 4 and his parents were told he was off the charts. His mom was going to put him into the gifted program (she had to go through a lot to do it, which I think has changed for the better). But she viewed a class and the kindergarden teacher screamed at a child for not knowing the answer to a question. She couldn't believe what she witnessed and did not want her son to have the same teacher. So they decided to put him into some of the best private schools in Manhattan. But they didn't have a gifted program, the best private schools in Manhattan but it was all mainstream learning. He always excelled in school but when he reached junior high he started to have problems at school. Everything that he went through were classic examples of a gifted child that gets bored and begins acting out. When I met him he had completed 2 years of college on and off but couldn't get himself to go back. He still claims that being in a classroom makes him physically ill. After reading up on gifted children and the research they have done I finally realized and understood why he could not finish college and why it made him ill. Which is why now that my son is thought to be gifted I am very concerned with his education. He is a lot like his father and I do not wish for him to run into the same problems my husband did. The gifted school here in Buffalo that my son will be testing at next year has some great information on this subject.
Here are the links.
