State ASSESSMENTS are NOT the same animal as TESTS. The state assessments are required by the Federal "No Child Left Behind" Act. They are the accountability factor. They drive the curriculum and I can guarantee you that your child will not be able to "pass" unless he or she has the "correct" worldview and values. The open ended essay portions of these instrumants are the stumbling blocks. Answers based on "your morals and standards" will find your child incompetent by the "federal standards". The multiple choice questions chip away at beliefs by making the child choose the least problematic of several grey area options.
Home-schoolers have outscored many public school students for years, on tests of academic skills. Testing is not a problem but Assessing the value of your child to "their" public government school system is.
And guess what? Homeschoolers are exempt from these "assessments" under the No Child Left Behind Act thanks to HSLDA.org.
