2. Every school day, more than 7,000 students drop out of high school (Pinkus, 2006). Only 70% of high school students graduate on time with a regular diploma, and fewer than 60% of African-American and Latino students do so (Greene & Winters, 2005). Students who enter ninth grade in the lowest 25% of their class are 20 times more likely to drop out than are the highest- performing students (Carnevale, 2001). Nearly one third of high school graduates are not ready for college-level English composition courses (ACT, 2005). Over half of adults scoring at the lowest literacy levels are dropouts, and almost a quarter of these persons are high school graduates (National Center for Education Statistics, 2005). College instructors estimate that 50% of high school graduates are not prepared for college-level writing (Achieve, Inc., 2005). U.S. graduates’ literacy skills are lower than those of graduates in most industrialized nations, comparable only to the skills of graduates in Chile, Poland, Portugal, and Slovenia (OECD, 2000).

3. Thirty-five percent of high school graduates in college and 38% of high school graduates in the work force feel their writing does not meet expectations for quality (Achieve, Inc., 2005). About half of private employers and more than 60% of state government employers say writing skills impact promotion decisions (National Commission on Writing, 2004, 2005). “Poorly written applications are likely to doom candidates’ chances for employment” (National Commission on Writing, 2005, p. 4). Writing remediation costs American businesses as much as $3.1 billion annually (National Commission on Writing, 2004).
