There are many test developers, schools, and curriculum publishers offering free and non-free standardized assessments, skills tests, and placement tests. Placement tests are generally designed to help you place your child in a suitable grade or purchase appropriate course materials, but they can also be used to discover how much your child already knows, identify skills your child hasn't mastered, or verify that your child is ready to advance to the next level. This is a short list of websites offering free printable, downloadable, or online placement tests. Nationally normed standardized test providers and more assessment resources can be found on iamhomeschooling.com.
