Homespun Schoolhouse of Agapé
“Public and private schools frequently test or evaluate homeschooled children who are entering or re-entering their school. They have the right to do this to determine grade placement and to decide whether credit should be given for work done in the home school.
Homeschooled children of any age or grade level may be tested when they enter or re-enter school. In our experience, early elementary and high school aged children are most likely to be tested, as are children who have been labeled as Gifted/Talented or Learning Disabled. Some school divisions may routinely test or evaluate all incoming homeschooling children, regardless of age, grade, or ability level. A school division's decision to test your child should not be seen as a reflection on your parenting or homeschooling abilities.
Parents who provide home instruction to their child are required to provide annual proof of progress, either in the form of testing or evaluation (§22.1-254.1 C). If you homeschool your child for a year, then send him back to school the following year, you are still required to submit annual proof of progress for your homeschool year, even if you know that the school will test him again upon his return to school.”
