Hi everyone, me with more questions. 

 How often is it recommended to test your gifted child?  
The reason I ask, I'll give a little background, DD then 5 started K last September, we had her tested (a MS through the school)  to see if she needed a grade skip,she did.  That was in November.  We since have had an IQ and achievement testing.  I was going over the achievement testing and noticed that she improved 2 grades in all subjects she had been tested in November, so 8 months ago.
  At some point do they slow down? Or is this the type of learning speed she has a grade every 4 months?  How often do you test?  Or what is recommended? It almost seems like you need to test at least once a year to track their process and find out what type of materal should be taught.  An example on that is in November she was tested at a 5th grade reading level so I was purchasing books for her to fit that, recently she's been telling me she wants different type of reading material, so I let her pick it out , she picked out a science encyclopedia, I purchased it but I thought might be too hard, It turns out now she reads at a 7th grade level so it makes sense she wants more complex material.
Thanks in advanced for you replies!
