I am an elementary school principal and from my perspective I feel that it is helpful to know from parents some of the following things about their child:
-special topics that interest your child, there may be a teacher with a particular passion that matches your child's interest.
-what type of environment your child likes related to classrooms and teaching styles (e.g. low key, predictable, prefers routine or more spur of the moment, go with the flow)
-include information about whether your child warms up to people quickly, is trusting or takes time to open up.
-you may also want to include your vision of a successful K year for DD, what do you want for your child.
As an educator I would appreciate having the WIPPSI scores, it can really speed up the 'discovery' phase of getting to know your child as a learner.
I hope this helps.
