According to Education Northwest's website, The 6+1 Trait® Writing Model of Instruction & Assessment provides a common language for teachers and students to communicate about the characteristics of writing and establishes a clear vision of what good writing looks like. Pioneered by Education Northwest more than 20 years ago, the 6+1 Traits continue to help thousands of teachers worldwide who have been trained in the model improve their writing instruction, their understanding of the qualities of good writing, and their ability to provide effective feedback to students.
