There are many professions within the field of education and just as many online graduate programs to match them.
Programs include year-long certifications and diplomas, two-year master's and multi-year doctorates, which are offered by public, private and for-profit universities. Most online programs run on the quarter system with start dates throughout the year. Areas of specialty include teaching and curriculum, education policy, special education, student development, grade-specific teaching certification, educational leadership and management, higher education and learning technologies.
Specifically, the University of California's Rossier School offers a Master of Arts in TESOL (Teaching English to Speakers of Other Language) while Drexel University, based in Philadelphia, offers a Master of Science in Global and International Education for those interested in a wider scope of study.
