Open enrollment for the X for Teachers Program is available through June 30. The program has been expanded beyond K-12 teachers; membership is now open to all full-time K-12 educators including faculty, instructional staff, and administrators as well as all colleges of education faculty, staff, and students, reports Mac Using Educators. The program — which focuses on resources and tools that maximize Mac OS X in the classroom — runs during the summer and is free (however, it doesn’t include a free copy of Mac OS X).
