Testing does give an idea of strengths, weaknesses, and learning styles of children. Sometimes it can give us an idea of perfectionism and if there are learning disabilities.
I always encourage parents for the individual testing because it does help give them a good indication of the best learning approaches for their child. I don’t advocate for more testing but this type of testing can often be perceived as fun by children and helpful to parents and educators.
For gifted parents, I found this easy chart today to give you a general idea of how the scores can be explained. Very general!
