Getting called into the boss's office isn't always fun. Memories of trips to the school principal's office flash through one's mind. But the day last year that the author was called in to meet with their division vice president turned out to be a very good day. Executives at his company, Microsoft, had noticed the program he created in his spare time to train and place industry professionals as volunteer computer science (CS) teachers at local schools. They thought it was a great idea that needed to grow. So the author was offered the chance to run the program full-time, with backing from the company. Thus the Technology Education and Literacy in Schools (TEALS) program was "officially" born. This school year, there are 110 TEALS volunteers--mostly from Microsoft, but with about 20 percent coming from other technology companies--working with teachers in 37 high schools to teach computer science to more than 2,000 students. The program operates primarily in Puget Sound-area schools, but now extends from coast to coast, with participating schools in California, Utah, Minnesota, Washington, DC, Virginia, North Dakota and Kentucky. The ultimate goal of the TEALS program is to become truly nationwide; to leverage the passion and skills of high-tech professionals while keeping their day job; and to bring in-service teachers up to speed on the latest in computer science and the impact of it on their students' daily lives. TEALS works because the entire school ecosystem comes together to make computer science classes available to students. It requires supportive administrators, counselors and in-service teachers committed to developing these critical skills in their students. It also requires a flexible employer and a volunteer who is willing to dedicate at least 300 hours per year for an experience that they will carry for the rest of their lives, and at the same time, become an advocate for CS education.
