There are thousands of inexperienced parents across America allowing their kids to opt out of testing this week and every year now it seems, with all sorts of reasons ranging from the testing being too rigorous, to it's too time consuming for the kids, to the idea that someone is making money off the testing.
Now the bad news... next to your kids' classroom, there is another classroom filled with kids the same ages as your kids, who are doing a gifted or advanced class. These kids are not smarter than your kids...
This is the class you want to get your child into, because these kids will have different entities, non profits, and fortune 500 corporations offering to pay fully for their college costs, with the after college possibility of going to work immediately for the corporation or being placed in a job immediately upon graduation. All for free.
When you refuse to have your child do the tests, they will not be accepted into a gifted or advanced kids program. You are forcing your child to stay in a regular class and miss out on the extra help that the advanced kids receive.
