The author has years of experience in TExES test development and in providing popular, successful, and inspiring TExES preparation seminars at multiple universities and training sites around the state. The student development concepts upon which TExES is constructed is written in a down-to-earth manner utilizing real life stories for practical application and will allow the reader to connect theory with actual practice.
