We are testing this morning.  A friend directed me to www.FamilyLearning.org .  It is a homeschool consulting organization that also supplies testing materials to homeschool families.  They provide the test booklet, answer sheets, and examiner manual.  You have 2 weeks to administer the test and send it back for them to grade and score. 

I've been homeschooling my oldest son for4 years and this is our first standardized test.  I guess it's a good time.  We're getting ready to move more toward the Charlotte Mason style.  This is a good marking point of sorts.
