As they begin taking classes, most incoming adult learners express a strong desire to complete a degree, but many also harbor concerns and attitudes that reduce their motivation and put them at risk for attrition. This report explores a wide range of these noncognitive, motivational attributes that influence completion. The study is based on a national sample of 5,000 first-year adult learners who filled out a 74-item, college completion risk survey in 2014 or 2015 at 50 colleges and universities across the United States.
