The Tennessee Electronic Library provides free Praxis I and Praxis II practice tests.
TEL is free to everyone in Tennessee. It's paid for by the State Library and includes test prep from Learning Express Library. There are two versions of the Praxis I and Praxis II practice tests, including segments on Early Childhood, Elementary, and Middle School education. Tests are timed to simulate real-world conditions, and scores are available immediately.
