Who wants to send their kid to a school with no tests or grades?

It's called a "democratic" school -- democratic because students are “self-directed,” and vote on what they'll do every day.

Plans for one such school are reportedly in the works for students in the Boston metro area.  The Joan Rubin School will be a non-profit day school where students "will not be graded, nor will they be tested or separated into classrooms," the Metro reports.

“One size doesn’t fit all when it comes to schools. I think kids in the city need access to a school like this,” said Cambridge resident Brooke Newman, 35, who is one of the founders of The Joan Rubin School...

“There is no real teaching… all the learning comes from the intrinsic motivation of the children,” said Newman.

Having attended Sudbury Valley School in Framingham, a school that practices a similar democratic learning model, Newman maintains a strong belief that Boston needs the alternative learning environment, which she believe will encourages freedom, trust, and respect. ...

The school, which is named after Sudbury Valley Founder Joan Rubin, will be open to students between the ages of 5 and 19, and may take about 200 students. The age groups will not be separated, Newman said. Instead, pupils will be encouraged to mentor and learn from each other.
