The District’s Writing Scoring Guide was used to assess prompted writing samples from laptop and control students. At the end of each school year, students wrote a letter of introduction to next year’s teacher. These letters were collected and scored with the rubric. Experienced reviewers used the district’s four-point rubric (ranging from 1 to 4, with 4 being the highest rating possible) to conduct a blind assessment of the writing samples for Ideas and Content, Organization and Form, Style, and Conventions, yielding four scores per student.
