No Tests, No Grades
Roughly 300 public schools in the U.S. follow the teaching principles developed almost 100 years ago by Italian physician and educator Maria Montessori.
This method stresses small group instruction that allows children to choose their own developmentally appropriate activities and learn at their own pace. There is no testing and no grading.
Montessori is primarily used in preschool and early education settings, but there are also Montessori middle schools and high schools.
