I have wondered about this too what test/whether to test so young. My dd3 just started preschool, and I am afraid she is already (before school started) hiding what she is capable of, in some circumstances.
I think the preschool we picked is excellent and hopefully will reduce some of this rather than cement it further, but if that is a concern (gt kids hiding skills more and more as they move up through school grades) then I could definitely see testing sooner rather than / in addition to later.
