The availability of AR (Accelerated Reader) tests for homeschooled children depends entirely on whether their parents or guardians choose to subscribe to the program and have access to it. AR is not a public, universally available testing system. It's a proprietary program offered by Renaissance Learning.
Homeschooling families can purchase access to the AR program, giving their children access to the tests and associated resources. However, it's not compulsory or free; it's a paid service. Therefore, while AR tests *can* be accessed by homeschooled children, it's not guaranteed.
