With her movie’s grass-roots success, Ms. Abeles has been approached by major distributors offering to place it in commercial theaters. But she is not convinced that the movie would reach as wide an audience or inspire viewers to stay for the discussions, which are moderated by principals, child psychologists and sometimes Ms. Abeles herself. The film’s Web site encourages viewers to follow up with local activism (and also links to research and studies supporting the film, which pretty much avoids citing any data).

“My passion is around the change this film has the potential to create,” Ms. Abeles said.

While “Waiting for Superman” lionizes urban reformers who embrace standardized testing as a necessary yardstick to hold schools and teachers accountable, Ms. Abeles believes that the testing movement is what has caused education to go off the tracks.

She talks to students, teachers and experts who say that teaching to tests, including the Advanced Placement tests, narrows education and diminishes creativity and independent thinking. Employers complain that college graduates these days lack initiative. An educator, Denise Pope, a lecturer at Stanford, says that the University of California requires remedial courses of half its students, even though their high school grades were stellar.

“They’re spitting back but not retaining the information,” Dr. Pope said.

Most of the families in “Race to Nowhere” are suburban and privileged, and the film has found its audience in those communities where parents often move for excellent schools. In addition to New Canaan and Winnetka, there were screenings last week in Los Altos, Calif., Bethesda, Md., and Chappaqua, N.Y.  towns where an Ivy League sticker on the back of a Range Rover is a given.

“You would not believe what reactions you get from other parents when you mention what colleges your children are looking at  you’re so judged,” Tara Vessels, a mother at New Canaan Country School, told about 40 other parents and staff members who discussed the movie last Friday in the school cafeteria.

The school espouses a “whole child” philosophy, and its mission statement, inscribed on the cafeteria walls, includes the sentence: “We value the imagination and curiosity of children and respect childhood as an integral part of life.”

But parents said the larger community imposed its own values, and their children clamored to join an ice hockey league that practices until 10 p.m.
