Her teaching credentials are long and star-studded. Rachel has the uncanny ability to "get through" to students of all ages. She is a master at teaching students how to take tests, something that is almost as important as knowledge of the subject matter itself.None of Dr. Wilken's students have ever failed the TEAMS, TAAS, TAKS, ACT or SAT tests. Several years ago she discovered an error in the way the "main idea" was being taught. She was recognized by the Texas Board of Education and it resulted in a rewrite of textbooks nationwide. Rachel holds a lifetime Texas teaching certificate and is a Distinguished Fellow of the American Board of Master Educators. Her teaching honors include being selected as the 2000 Caller Times Teacher of the Year. She is a member of the American Federation of Teachers.
