Clovis is a city of about 100,000 thousand people near Fresno. Its school district covers almost 200 square miles and serves more than 41,000 students. But it's quite different than other California school districts in one essential way. It has no teachers union -- and the teachers like it that way. In this edition of Zócalo's Connecting California, Joe Mathews says the Clovis experiment offers an alternative, less contentious, model for delivering public education. It may not be suitable for every district in the state, but it shows that teachers need not pay union dues in order to get organized.
