This scientific study conducted in 74 Oregon elementary schools showed that the 6+1 Trait Writing model caused a statistically significant increase in student writing scores during the year in which it was studied. The REL Northwest study, published in December 2011, examined first-year implementation of the model, in which teachers were provided with additional writing instruction and assessment strategies that were intended to complement whatever writing curricula and strategies were already in use at their schools. Researchers found that when implemented under similar conditions the writing model could be expected to raise the average level of fifth-grade student writing achievement from the 50th to the 54th percentile. The two-year randomized controlled trial involved 102 teachers and 2,230 students in the treatment condition and 94 teachers and 1,931 students in the control condition.
