Medvedev said preteen students at about 12,000 schools in 18 Russian regions would take the classes. They will be offered the choice of studying the dominant Russian Orthodox religion, Islam, Buddhism or Judaism, or of taking an overview of all four faiths, or a course in secular ethics. Students and their parents must be allowed to choose freely, Medvedev said in addressing top clerics and officials at his residence outside Moscow. "Any coercion, pressure will be absolutely unacceptable and counterproductive," he said.

By 2012, the classes might be expanded nationwide, Medvedev said. The pilot project includes about 20 percent of Russia's schools. The offer of a choice appeared aimed to ease concerns that Russian Orthodoxy will be forced on schoolchildren as the church gains influence and tightens ties with the state. Mandatory classes in Orthodox culture were introduced in a few Russian regions three years ago, but they alarmed adherents of other confessions who said religion has no place in schools in a secular state. The classes also were criticized as being reminiscent of the forced study of communism or scientific atheism during Soviet times, with one mandatory ideology being substituted with another.
