William Zaggle
William H. Zaggle is a founding partner of Excelsior Software, Inc. and currently serves as the president. Zaggle helped lead Excelsior Software to become one of the leading educational technology companies. This progress has stemmed from a sincere commitment to raising student achievement by providing immediate access to performance information, increasing teacher productivity, and improving parent to home communication. As an early pioneer of the electronic gradebook concept, Excelsior Software delivered the technical innovations that drive much of today's focus on data-driven decision-making in education. Excelsior created the first Windows based electronic gradebook in 1991, the first home-school network connections showing real-time student progress in 1993, the first web based parent portal with real-time student grades in 1996, and the first enterprise level implementation of a gradebook in a single school district with over 20,000 teachers. Currently, Excelsior works with educators in nearly 1,000 districts nationwide.
Prior to his work at Excelsior Software, Zaggle directed day-to-day software projects for Heating and Ventilating Engineering work at Elite Software Inc. Zaggle began his career at Texas A&M University as a researcher and instructor. Zaggle received the Oppenheimer award for best computer graphics design concepts in 1978-79. He has authored several works on computer graphics and graphics database management.
